Be careful. Even Butterfly and Stiga sell some flimsy, less than optimal tables. See what's available locally first, and then start looking online - vendors such as Amazon and Wal-Mart. Do factor in shipping, and in what shape said table arrives in (in many cases, lots of assembly needed). Be suspicious of anything costing less than USD500 - most of these are flimsy. The Kettler's an outdoor table and if you do a search you'll find posts where people don't like the bounce (it bounces less than the optimal indoor tables). However, if you do need something that you can leave out in the rain it might be a good choice.
Killerspin has a reputation for high quality, over-the-top stuff, don't know if that applies to their tables.
By the way... if you see a bat holder attached to a table, it's a really bad sign...
