I recently bought a 3DS, and I've had my eye on the R4i 3DS RTS. I've seen many different sellers, all with various reviews and suggestions, mostly on this site. I've never owned a flash cart, and the RTS seemed the best, saying that I also use a DSLite. I've looked at 20+ sites, and I can't tell which one to use. I'm kind of cheap, so I'm definitely looking for something below $30 or $25. Any suggestions?
