used dry suit..good idea? or bad?

[dbarlow]

As many of you have figured out by my line of questions I am still pretty new to the sport and I am still building my goodie bag.

I have been looking at used dry suites on ebay and I am tempted but would like to know what everyone thinks.  I would love to be able to try them on and see how they fit but this of course is not going to happen. 

I have had good luck for the most part with stuff I have bought one ebay but I usually also have en ebay rule that I live by. don't buy it unless you can afford to loose the money you are sending into the great  unknown.

What are the good brands? DUI probably not an option at that price...

How much would you spend on a used suite?

Let the knowlage flowwwwwwwwww.

Thanks

Doug
