Trek has been raising prices and pulling a switcher-roo. For example, today's' stock components of the 7.6 are what - many of them - came on my 2007 7.5. Carbon-fork, Tiagra RD, better-grade handlebars, etc. I paid $710 for my 2007 FX in early 2008 - they were making room for the new stock. Now the 7.5 FX has gone up to $899+ and it's components are what, at the time, were on the 7.3 FX (really nice bike - I should have gone for that!). So you have an excellent machine there.

Not that Trek are crooks - all the FX-series are very fine bicycles. It's the economy crashing and burning on all involved - from the Trek factory's manufacturing costs to the retailer and so on. But if someone states they want to customize a new FX, and which should they buy - nowadays I counsel to go with the 7.3. Costs of a full customization can be exorbitant - starting low-price helps offset this. And looking about for a frame, of the hybrid school of design, and building up another hybrid for resale also helps.

And so does being a skilled bike-mechanic.
