This is where I ordered mine and they are a great place to order from. Very fast.

Dealextreme. Ordered loads of stuff from there and never had a problem. I'm in the UK too and the shipping time is reasonable considering it's coming from china. Never had to wait longer than 2-3 weeks.

For an overview of the available carts check out the Pocketheaven Wiki:

Having bought an M3 Real Perfect bundle for my DS, If there's a GBA version it's probably pretty close to the best. That being said, for GBA I love my Supercard MiniSD. It's affordable and works pretty good. It's certainly not the best, but with the right patching it can do nearly everything you'd need it to (all types of regular GBA battery saves, realtime save, cheat database, etc). It has built-in emulators for NES, GB/C, GG, SMS and PCE (so you just put the roms on to the up-to 16 GB card and it plays them). There are only a handfull of games that get any lag with the latest firmware. The rest with the right patching options work flawlessly at full-speed. I've built 6 GBMs with Supercard MiniSDs for friends who played mine and then wanted one of their own. Having bought 8 Supercards, one turned up dead. It was promptly replaced.

From memory the games that don't play well on it no matter what are:
Street Fighter II
King of Fighters EXII
Tekken
Grand Theft Auto
Mario Kart Super Circuit

There's a few more that need to be Quick Power Cycled to save their games (meaning the saver patch messes them up).
Still that leaves thousands of GBA games plus the 10s of thousands of emulated games that can all be fit on one cart.
I've built a nearly perfect 1GB block of games so if you go that route PM me.
I get all mine from gamersection.ca - they have fast delivery and no fake hardware. Watch out for places not on the official supercard.cn list of reputable dealers. The fake carts suck and barely ever work.

gamersection.ca looks good, but they only have supercard SD, not Mini SD. I heard that the regular SD version sticks out of the GBA SP quite a bit. Not flush like a regular GBA game. Is that true?

Yes, it sticks out about 3/16" on any GBA. With an SP it's not too bad. That's the first one I bought.
Here's a list of official dealers:

So I dont think my question has actually been answered. Where can I order a Supercard Mini SD from? Obviously I've done some googling, but I'm looking to not get ripped off, and to not order from some unreliable place. I'm in the US if that makes a difference as well. Thanks.

RealHotStuff is a good merchant to buy from.

Thanks, man. And $24 is reasonable... only thing that worries me is the last line of the description, which says no GBA support[b][/b] what's up with that?

Yeah, I saw that. I have to think that they (RHS) are wrong. On the official SuperCard website, it claims GBA support.

You might want to send RHS an email asking for clarification.

my confusion is what "GBA support" means.

If they're talking ROMS, then I don't care. I don't bother with ROMS.

If they mean "this cart only works in a DS, NOT in a GBA" then there's a problem.
