Congratulations and welcome to the board! Hopefully you don\'t have to wait long ;-)
As far as I know, you can install the Cacko-Rom as well from sd as from cf.
cf-cards are faster and much cheaper. Still, I\'d advise you to buy a sd card, because you\'ll need the cf-slot for other cards: wlan, bt, gps etc.
This way, you could just leave the sd card in it\'s slot without bothering too much about space and card swapping.
cheers, Kathrin
