I'd suggest you switch now, and use last year's number as your budget number. You're sure to be beneath that, and the extra can be thrown at something or saved (like for Italy!) You don't want them to have an interest free loan!

(and WOW on the usage! I'd like to look at those new strips you have next time I'm over, I'm considering one for the living room and the DVR, or hopefully at some point a media PC)
