Inversion Tables

Okay,I've been doing some researches on the In.tables and

so far I've looked at three of them.One is a Healthware

model,another is by Bodyflux and the third is a Lifegear

model.The Healthware model seems to be the sturdiest.

Can someone give me any input on this as I have absolutely

no experience with this equiptment.I also noticed some up

for sale on Craigslist and they looked fine.Is there any

pitfalls in buying a used one?

Thanks for any advice. Tweet
