I've got a whole cabinet of oldish collectables that see some action and a Canon EOS DLSR/35mm system. I really don't have a "setup".. I just pack whatever suites my purpose or mood. Packing too heavy can really ruin the experience....
For starters... I'd go with simple...
* DSLR or Film SLR (your preference) Can't go wrong with either Nikon or Canon... Even the consumer line of cameras are great nowadays
* Shoulder bag. Lowepro or Tamrac are popular. I like Lowepro
* Medium Zoom and a fast 50mm prime. Most of your budget is best spent on the glass. Canon's 50mm f1.8 is far south of $100.
* Lightweight tripod... if you choose to do so.
My cousin started out with the following a several years ago and it still fits him well today: Canon Elan II, 28-135 IS USM, 50mm f1.8,
adorama shoulder bag (he doesn't like to use tripods...).
If I'm not going on a long hike and feel like shooting B&W negative I tend to pack Pentax 645 w/ 55mm, 75mm, 105mm and Pentax LX w/ 40mm pancake and a medium zoom. I enjoy that "setup" a lot .. sometimes more than my fancy up-to-date Canon digital.
