Flash Carts

I've got money, and I want one for my GBA SP, but there's a ton of out there, so I wanna know which flash cart is best in terms of how well it deals with roms, the quality of cart itself and the software that goes with it, etc...

I found an Elink 512m flash cart for $22, but are there other brands that are better?

Go to GBAtemp.net, and ask it there

EZ-Flash IV is pretty good.

Get a Supercard (look it up in Google). I have one for my DS and it works great, they make some for GBA too.
