If you are not sure if it will suit you, order from amazon, try it for yourself, and if you don´t like it, send it back. I know i kept mine (S), but maybe you think different (and its fine). :thumbup:
Edit: oh, i forgot to add i had a cv1 to compare with, i sold it later for 225€ so upgrade operation was 225€, imo was worth it every €, its impresive value for the money.
