Last steel Boulder was a 2002; and only the seat tube was chromoloy - - the other tubes are hi-tensile steel (read: heavy) and had a rigid fork. $180 seems high to me.
If the DB has a suspension fork (Suntour?) it's newer and should be an aluminum frame, right? If that's all the case, I'd go for the DB.
