The below is from BBTunas infamous table comparison thread on this board. He is pretty much on the money (no pun intended) with his review and price estimates. Hope this helps.
Blonde – 1997 - 2001 This was the first color change at Valley ... it matched their ZD-7 pool table - $400-$550
consistent all the same, plays much different than the Brown Marble and has become my least favorite of all the tables
Cherry or Mahogany 2001 - 2003 Again this was changed to match the ZD-8 pool table - $450 - $650
Fastest of all the tables and because of this can be a challenge with ball control...
- I own this table, ball control is difficult but the speed is fun...play is improved with heat-treated rods but it doesn't really fix the control issues...however, if you can play on this table, you can play on any table...everything is easier after playing on this which in my mind makes it a good practice table
GREY MARBLES 2003 - 2007 - $400-$750
Overall, even with the quirks and all the confusing talk below about manufacturing changes, this is a really nice table.
30th Anniversary Grey Marble - 2003 release, only out during 2003
You can tell if it is a 30th Ann model because it will say 'Product of Valley' under the logo on the table surface.
This table really starts a wild string of table changes which are hard to document and follow but let me take a stab at it.
The Merkel heat-treated rods were introduced at this time...in my opinion the best table change I have seen on any table at any time - only rival now is the Warrior ball...the rods were very smooth, were almost unbendable, and required far less lube to keep them at their best
Issue 1: First tables released did not all have Merkel rods, there was a mix...some tables had none, some had some, some had all...this run of tables was fairly short so I don't think there were enough made at the end to be sure when ALL Merkel rods were available
Playing surface was a little different and many liked this table because it created extra control due to the surface change...
Issue 2: Before this run was done, the man changes began and spilled over to the beginning of the Grey Marble runs...there was an attempt to make a more durable cheaper man using Nylon (Lets call this Nylon 1) (pretty darn ironic since the Tornado man was already super durable)...Nylon set up differently in the molds so it created seam issues on the side of the man which impacted tic tacking and some had dips in the front and/or back of the foot - This first Nylon man was had a dull finish and is easy to pick out on a table,
They didn't give up on Nylon right away and so began Nylon 2 where they tried a different chemistry mix...still very inconsistent mold issues...this man is easy to pick out because it is very shinny ...
Both Nylon men were short-lived but still on the 30th and early Grey Marble to follow, there ended up being tables with some or all of the original man, Nylon 1, and/or Nylon 2 men
Grey Marble - 2004 to end of 2006 beginning 2007
Different playing surface than the 30th
Earliest versions had mix of men but were consistent with Merkel rods but less than a year in they had gone back to the original man and all Merkel rods...this was the best of the Grey Marbles...good playing solid table
Handles – went from shape which was well known and long running to wood with deeper dip, then to plastic with less dip, which was soundly rejected and short-lived, back to the original wood less dip
Rod - Part way through the life of this version Tornado dropped Merkel because they thought the rod was too expensive and went with an imported heat-treated rod...still better than the original rod but nothing near as good as the Merkel rods (Merkel is the last name of the person making them...made here in the US just for this application...Warrior is considering this in coming competition models)
Merkel rod side thought: How good is this rod? Played on a Brown Marble bar table which saw much non-fooser abuse...every bar table with non-merkel rods is going to have a bent 2 rod, just a matter of time and eventually the 3 rod as well...the owner of this table, without knowing it, replaced the 2 rods with Merkel and we played on that table for OVER 2 YEARS without the 2 rods ever bending...need I say more?
