My FX 7.4 with tax and a Bontrager computer was just over $900...but I'm sure I'll end up with at least $1200 in it by the time I get the gearing, etc. the way I want it!!!...I test rode an FX with the 2 front discs and didn't like it! I'm used to 24 speeds and didn't want to adjust to fewer gears...I know there's duplication of gear ratios with 27 gears, but imo, you get a different feel - depending on which front sprocket you're using to obtain the same gear ratio! (I'm sure gearing is a personal preference.)
I think bicycles are more confusing than digital photography!!!...i settled for a Rebel T2i and the Canon 100-400mm zoom...just over $2,000 for the pair...sounds like your budget is a little higher than mine, so maybe someone on here has a better idea than the Trek FX series.
