That's the beauty of a compact crankset. If you do it right the crankset is the only thing that you have to buy.
I replaced an Ultegra crankset on my Klein with an FSA Energy crank. I bought the Energy crank for an Octolink bottom bracket spindle so I didn't have to replace that. I lowered the front derailleur, resized the chain and reprogrammed my Flight Deck computer. The whole process only took me around an hour.
