do you mind telling us how much the course was? The website just seems to have a frontpage and contact :(
Trouble is, Neil's only running the course on a very ad-hoc basis - ie as & when he has time - maybe only twice a year, so it's not something you can easily book. If you're interested, best to drop him an email. Mark Bailey runs a similar course more or less monthly.
Cost depends on what you want to build, materials used, finish, etc, etc. I'd guess from £750 (really basic spec) upwards. Mine will have cost me around £1250 when all costs are added in.
