As much as id like one ive just bought 2 gig sd card for supercard sd so dont think ill bother (dont want to have to get new kit as well as i would be bothered about it sticking out)
Unless its purely the cosmetic consideration, I don't think you will be bothered by it sticking out at all. I just got my DSL a few days ago, and the first thing I did after charging up was put one of my EFALinker carts into the GBA slot and give it a go. I was pretty gung ho for getting a G6L for a long time, but once I was actually playing, the protruding GBA cart didn't bother me at all. I'm so tired of waiting for the G6L situation to resolve itself, so I decided to get something to "hold me over" until better things come along. I wouldn't want anything that sticks out any further than a std. GBA cart, but based on the feel of the EFA in my DSL, I went ahead and ordered a Supercard the same day. (SCminiSD & EFA - same size). I'm gonna use the Supercard now until the "holy grail" of DSL flashcart solutions is well established on the market (whatever that might be), and then I'll probably buy a couple of those, like I did with the EFA carts (perfect for GBA, by the way).
The DSL is very dramatic improvement. Whether its worth the money is a personal decision, but I think I like this machine better than any gaming box I've ever owned (and I'm 39 y.o.) I'll definitely be buying another one later on when other color options/special editions are around.
