Dave,
I really like it...so much so, there are two of them in my house. My daughter "borrowed" the first one so I ended up buying another. I wrote a pretty comprehensive review over at HC:

(It's the first review on the page.)
I haven't tried the MKIII version, but I'll bet it's pretty good as well.
Rick DeMarco has been great to work with. The first unit had a compenent go bad and Rick made it right in no time. He has been prompt in replying to email messages and the build didn't take too long either. I recommend his stuff (for whatever that's worth!)
