Further warning about MYOG.
I am a keen follower of those treads because some of the stuff folk come up with is indeed very clever. However I have also noticed that very often the final product is the third ,fourth (or whatever ) prototype and by then even an off the shelf top of the line version would have been a lot cheaper.
Of course for most , MYOG is done for fun as a hobby, but if it is just about saving money it may not work out as expected.
