I have a UMDK and it's a neat piece of hardware, but it sadly has some design flaws that make it hard to recommend. One problem is that it doesn't make use of the !CE0 signal (the main chip select for the cartridge) on the cart slot which means it will get into bus fights on systems with TMSS (Trademark Security Sysstem, i.e. the thing that displays the "Produced or Under License by Sega Enterprises, Ltd." text). The bigger problem is that it has issues with DMA transfers on a lot of systems resulting in severe graphical corruption in some cases.
