My comment on price was that you can get a higher top end gear (120 vs 115 or so) by going with 50x11 rather than 53x12 and it should cost you less. So you save money and have a higher top end gear. Now if you don't like your crankset, by all means replace that, it just seems that you can do almost the same just by replacing the cassette. Sure the gearing won't be as tight, but for me, that'd be enough.
