1. Lucky you inherited it, as anyone who pays $500 for a Park & Sun is getting ripped off -- its resale value can be no more than $50 to $100 at best.
2. It's a semi-clone of a mid-70s Tournament Soccer Bluetop, only with the rod configuration "lefty" style.
3. No one has played on Bluetop-style tables since the mid-70s, with the exception of a pocket of players in Seattle who continued to play on Mike Dickenson's very-well built Pro Soccer tables through the early 90s.
4. "Lefty" configured tables are not used in competition anywhere in the world.
5. The ball drop on the side who scores is, as noted in the above post, better for training/practice.
6. If it ends up you or your children don't play on it much or its taking up too much space, these tables are best donated to a youth club or something like that; but if donating be sure to buy and include with the donation a supply of extra men and nuts/bolts as they break really fast on these tables.
As a side note, "lefty" configured tables can be a good training tool for advanced players, particularly for improving concentration and coordination. At a game arcade that Tom Spear and myself co-owned many (repeat: MANY) years ago in Colorado, we had twelve tables, one of which was set up this way. The player who dominated most on it: multi-multi-multi-time World Champion Todd Loffredo. Then again, he was a mutant, but it sure was a crack-up to watch him do reverse brush passes, full-power pull-kicks and more.
My two cents...
