I haven't built one yet but it's a personal goal of mine once I've put away enough $$ for it. Reading about it is what got me back into rocketry, actually. At the time I couldn't afford HPR and didn't realize there was an "in-between". Always figured it was either Estes or big bucks.
(Yes, you kids out there, even us grown-ups often have to live with an "allowance"! I had more discretionary cash when I was in my twenties...)
