Hello, I'm very much interested too, I've only built one MFH chain set but am looking into higher end sets. Joeyko2000, your website has great pics and descriptions! Don't know if you've seen this yet or not, Jimbo, but check this link too:

From what I've seen, MFH are good for people on a budget but require a lot of cleaning up of the parts to achieve on par results.
Hobby Design is a slightly cheaper and apparantly easier to build version of Top Studio. But then Top Studio offer the most realistic finish in my opinion. I'm still undecided though...
