I know what you mean, too many choices about what to take. Mine is actually a 5x7 wooden field camera, but it's surprisingly light, and I find no worse to carry around than a DSLR all day. The kit consists of:
camera, 90mm and 210mm lenses with 5 film holders, filters, meter, change bag and extra film just in case and tripod
Not exactly stealthy, but against some of the stuff the digi guys lug around in their giant backpacks I quite often feel like I'm travelling light (if you've ever seen EdinburghGary in full lansdcape mode you'll know what I mean)
