FYI: WOOT has a deal today for the Teeter 560 model Inversion table for only $229.99. I just ordered one and with shipping the total came to $249.94.
Their ad says "blemished" but usually that's not a big deal - some of these are probably pre-owned and sent back after the buyer changed their mind - so they can't say they are "sparkly brand new".
