I'm looking at a getting a new bike for around $750 maximum ($600 if online to allow for duty and shipping), and I've hit a brick wall in figuring out which one to get. First, I was thinking of getting a Mountain Co-Op Chinook bike ($800), but then I found bikesdirect.com and now here are the bikes I'm looking at and what I think

Motobecane 700HT - good deal, but no choice in disc brakes is sort of a turn off
Motobecane 700DS - also a good deal, but sold out until october
Motobecane Fantom HT Trail - favorite so far, but sold out
Motobecane Fantom DS Trail - pricey, but keeping it in mind

Is there any other comparable bikes that I have missed, or should i look harder at the ones that I've looked at?
