I'd skip all the DLSR crap if you want to avoid the learning curve. There's little comparative benefit to having a DSLR over a cell phone or p-n-s when digiscoping. Just look at deerhunters photo above. There's so much compression at these distances and magnification that a DSLRs strengths such as shadow recovery and depth of field control are pretty much useless. Then there's the headache of packing it around all the time.
Get a pocket camera point-and-shoot that has a macro ability to focus on your spotters eyepiece adapter. For digiscoping purposes the primary determinant of image quality will be the ED/ULD/HD elements in your spotting scope, not any trivial crap in a bulky, klugey camera. Your lens forms your image.
