Question on used AG pool

I ran across a used AG pool on the local Craigs List. The guys does not seem to know much about the pool which does make me a bit nervous.

Here is what he says about the pool. "The pool has been in storage for three years and has been set up for only one year. The brand name is advantage and I got the pool, pump, filter, etc. as one package. Here is a web site that you can research the pool http://www.advantageman.com/".

Anybody know anything about that brand?

He is asking $200 for it and says he paid $1800 for it new 3 years ago. Thoughts, opinions??

Thanks!!
