I assembled a Castlewood kit about three years ago and it has been
playing ever since.  I found the design and quality of the kit
excellent.  It even comes with a small tubing cutter and an electronic
tuner.  As long as you can follow directions, and check as you go
along, you can do it.

There was only one minor problem -- one size of tubing supplied was
at the upper end of the diameter tolerance, and I wanted a tighter fit
on the nipples.  Castlewood would have sent me a piece of replacement
tubing, but I found same size-slightly tighter fit-at the local
independent hardware store for a couple dollars.
