I process my own c41, but not e6. There is very little to recommend processing your own film except cost and control. The former only if you do a lot and the latter can be negligible if you have a good lab near by.

When I'm in the UK I use the vault in Brighton for my colour processing, they do a good job and are nice folks. I have never used them for R prints nor do I know if they do them.

If you are going to make prints you may wish to shot neg film. The prints will be nicer, cheaper and easier to come by.
