Cyclocross - New frame questions?

Hey all, I'm glad I found this board, there's a wealth of info here.

I shipped my bike via Fedex Ground recently (big mistake). They lost it, found it and then destroyed it. :-( It was a 2001 Jake the Snake. I did insure the bike, but unfortunately Kona has upped the spec on the new Jakes and uses a new frame material so the insurance payment will not be enough to cover the cost of a replacement bike.

So I'm on a budget and I'm looking around for a decent ride for ~$800 or less if I can. I'm resorting to the internet as there aren't really any decent LBS' in my area.

Here's what I've found so far.

'01 Trek XO - 800
'01 Conquest - 750
'01 ZRX - 700

or I can pick up an Enemy frame for 300 or a Conquest Pro frame for 350

Does anyone have any comments on these bikes? Any leads to other good deals?

Thanks for your time!

I own an enemy that I have built up for racing this past season. I spec'd some pretty trick parts but even without those this thing rocks. The frame geometry is really likable and very responsive. It is fairly light and the aluminum rides very well. I had not expected such performance from a value priced frameset. You can also run discs on it which is pretty freakin cool. Mine has avid mechanicals with King hubs and XTR/Dura Ace parts. Good luck.
