so my r4 crapped out on me, first it made that funny spring-thing then a mate wanted to repair it. now it does not load anymore. but he is going to replace it with a flashkit of my choice. should i buy another r4, or go for one of the newer kinds? im kind of a power user, if a device has a feature i MUST use it im thinking of getting an acekard r.p.g. or cyclo evo.
