I think the most important thing is the washing machine
But you can get very good results with dslr's. since you're imaging from dark skies, you may not need exposures longer than 5 mins depending on the target. you can use dithering and darks to remove noise, as well as capture sufficient subs to increase your snr.
it all depends on your chip temperature as well.
Mike posted a link of some fantastic images taken with dslr's from dark skies, but almost all of them were at ambient temperatures below 20C. It was an uncooled modded camera with the IR filter removed.
as for the OAG look at these dslr's with the TS-9. you need just 9mm.

But your 9x50 finder should be good enough.
important thing is to start with a decent combo, learn as you go and then move on. I'm learning as well.
Else its a never ending slope until you end up with an AG12 with a large format CCD, a 2000 dollar focuser and a PMX mount or similar !!
