I've built one and loved it. Bruce Tharpe's kits are a real pleasure to work with and his cut parts have an exact fit. Plus if you have any questions or concerns, in my experience Bruce is alway there for you.

Checkout the Builders Update links. Or even do a search on RCU for reader feedback on the kit.
Cheers,
