Around 1989 or 1990 I bought a DJ-15 and liked it a lot. The beds seemed a little short, but with more practice and some good roller stands, I think I could have done a lot more with it than I did. I traded up to a DJ-20 and it's OK, but it seems like it's the DJ-15 is the one Delta machine I've had no complaints with. If you can find a nice used one, I think it would be a pretty good investment.
