Any stock table you find new for $200-$300 is worth maybe a hundred bucks. Don't do it.
If a racetrack is not a requirement (and I strongly advise against it), then your best bets for value are:
Build it yourself. A very nice oval with upscale materials can be constucted for $400 or so, and there are lots of folks here that can help ensure you avoid many of the first-timer pitfalls. A portable folding table-top can be built for around $150, and will far exceed the quality of anything you can purchase for twice as much.
Buy one from
@T_Chan ChanMan Tables. His basic tables are incredibly priced, even when including shipping costs.
Find a local table builder and have him build one to your specs. Cost would likely be close to what you'd pay Tony, maybe a tad less.
Get lucky and find an incredible deal on craigslist or letgo, and hope it's a solid build in good shape and you don't get rolled during the cash transaction. Definitely buyer beware with this option.
If you can't afford any of those choices right now, then spend $40 shipped for a 72" oval neoprene roll-up table-topper, and put the rest of your budget money away until you have saved enough for one of the first three options listed above.
Bottom line: Don't settle for something subpar that costs you a high percentage of your budget. Save that cash for the real deal, and you'll save money (and be happier) in the long run.
