RecRider,
I took a look at those models you are considering.

Did you take a look at the Trek 6500? It is an entry level 9 speed. The other bikes you were looking at are all 8 speed rears.

It looks like the models you are looking at are fairly old technology. I wouldn't pay that much for them personally. It looks like Cdale and Trek are clearing out their parts bins on those models.

I prefer Shimano shifters to SRam myself. I have had both and much prefer the Shimano.
