Well... I just lucked out hard. I ordered an MK1 for my DS in a moment of weakness (I had held out for this long so far, because I KNEW the technology would suck when it first came out, as I had experienced the same exact thing with my early GBA flashcarts).
Luckally, the company I ordered from was out of stock with the MK1's, and after a bit of research, I realized that wasn't what I would want anyways. As I was doing research, I realized that the MK3 2006 was just released the same day, so I snatched it in my continued moment of weakness, instead of waiting till everyone in the forums here or somewhere else explained that: "everything works! the software and the hardware! couldn't be easier to use! everything's figured out 100% and perfect now...".
Before I even ordered I knew it would be buggy, but it worked enough to play most games, so I thought it would be a good enough time to jump on the bandwagon.
I'm sure if you asked the right person too, you could get a copy of the Menu V0.6_A2 if you really needed it... But from my experience, Beta programs suck and aren't worth trying, and the fact that the title has an "A2" in it means to me it's the second Alpha, which would work much less. The only thing I've really been able to use Menu 0.6_A2 for is to run homebrew stuff, since version 0.4 doesn't seem to have the ability to use the touchpad in homebrew. The Menu 0.6_A2 program doesn't even have the ability to flash games to the internal memory of the MK3. It just locks up when you ask it to.
On top of that, the Slimloader IV also doesn't work, so I had to use one of my very old (and when I purchased it, VERY overpriced) F2A flashcarts to test the alpha version menu interface out.
Even though I started by not doing this enough (obviously), you really need to research products before you buy them, and decide for yourself (and with the help of some biased opinions of people who might have bought them already) if the product is right for you.
I feel for you though if you did get stuck with an older model. I spent $4 grand on a killer computer, right before the next wave of killer computers came out, and now I'm sittin high and dry with a computer that cost more than some of my friends cars, but doesn't even have a dual core.
