DIY tube amps

I'm wondering about other members experience with some of the "build it yourself" tube amp kits out on the market. I'm using SS mono blocs at the moment, and am quite interested in going the tube route, but am also liking the idea of trying my hand at building them myself. As a bike builder, I am quite handy, so to speak, but I am not an electronics guy. Recommendations? Oh, and bye the way, I have some fairly hungry speakers (Wilson Audio), so low powered amps won't do.
I had a blast building a Sun Audio 2a3 stereo amp kit.  That was easy to build, but only 3.5 watts or so.  Got me into tubes from solid state.
Get a Scott LK-150. Upgrade the coupling capacitors & rebuild the power supplies. Great sound, power no problem.
