Off Axis Optics

I am very much interested in observing details of Jupiter and the Moon. So I am now thinking about building off axis newtonian telescope because I want the sharpest view, but don`t want to bring about very large diameter reflector telescope with off axis mask nor to pay much money for good refractor. Are there any better ideas?

As for off axis mirror, I am wondering how to make the mirror myself. Do I have to cut the larger mirror in a few pieces after grinding it without any stress??? It sounds too difficult for me. Does anybody know any other ways to make off axis mirror?

My other options is to use normal newtonian mirror with very long focal length (say f10? or more)or to buy off axis mirror from DGM Optics.
Does any body tries DGM Optics? Is the view through DGM superior to any other newtonian with similar size and comparable to that of good refractor?

Any comments about off axis optics are appreciated.
