Another Air ride question

[tiggfall]

For those of you that still like or still have your factory air ride system and if you have replaced your rear air bags, what kind did you go with. I have came across a few different kinds off ebay from $86 a pair to some other web sites charging up (and more) $130each bag.
What is the difference or is there a difference because they all say basically same thing in the description.

What have others used?

I have only owned my 98 Expy for a few months, but I have been buying from Arnott. The main thing is to buy the right ones. Some are for 2 wheel drive and some are for 4 wheel drive. Usually the cheaper ones are for 2 wheel drive.
