GBA/SP Flash linker & cartridge

Yeah I could use an emulator, but I don't want to.

I became interested in GBA development about a year ago and I think I posted something about it once, but that's besides the point.

I can't find any dealers that have flash cartridges or link cables in stock, but then again I don't know what I need to buy exactly.

So this is a cry for help aimed at anyone with any experience using this hardware for GBA dev; what should I get? Where from? How much should I spend (I did notice the prices seem to fluctuate quite wildly)?

No takers? Not even one?
Well I'll dig deeper this afternoon since I've got the time.

I got the flash cart for my DS here; they probably have the stuff for GBAs too.

Used to be able to get stuff from lik-sang but I guess that's a no-go now...
