Ok so let's answer a few of your questions, 1st pic looks like an early gen whirlwind like the one I learned on. Has a dark cabinet etc.. 2nd pic is a new gen whirlwind..The classic is a table that's only been out 6-7 years maybe, I think they compare that to the old cyclone which is just a step below a coin-op. I would go with the classic, how thick are the sudewalls on it? Does it have hexagon 2 piece bearings? Both signs of a quality table. Hope this helps,
