I've bought a cheap 6V71 off a train and currently have so many projects that I wouldn't mind spending some $$ to skip hours of googling and learning how to convert it.
Dean's name/shop comes up a lot when googling blower stuff so could assume it's good info on the CD, but when I go to his website it looks like it's made by some student in the early 90's and full of grammar errors and some pages just 404.. Is the CD like that too? I don't think the $30 is bad price at all for professional information, but if it's laid out as bad as the website is...
