Continuing the thread hijack....I read a negative review on the Bike Friday that said after reconstituting it, that the derailleur always needed to be readjusted. In y'all's experience, any truth to that? My guess is not, but I've been trying to find opinions, both positive and negative.

Background...I just bought a custom bike. The fit is wonderful and very much non-standard. I take 1-3 bike vacations a year so I figure I have 3 options...take my beautiful new custom in a big box, paying upwards of $250/trip and risk TSA and baggage handler damage, continue renting bikes that can never fit for upwards of $250/trip, or, seriously contemplate a Bike Friday. I have to admin the latter idea is intriguing. This thread has me thinking it should be a plan and I should start saving the pennies.

Any negatives?
