Kodak 2D's, Koronas, or Burk and James' wood view cameras would be good choices. Some of these don't have much for movements but they can be folded to relatively compact packages and can be had within your budget of 1K, including a lens and some holders, though reducing backs might increase that some. They are light enough to carry around easily, though adding tripod, optics, and holders will increase the weight and bulk of anything considerably.
You might also consider a 5x7, the negative is big enough for a decent contact print, but holders and film are much less dear than 8x10. Some lenses that are good for 4x5 also cover 5x7, for example the Schneider Symmar 210. A 210 is a good portrait and general use long-ish lens for 4x5 and more or less "normal" for 5x7.
If you aren't going to carry it much a Calumet C1 "Green Monster" 8x10 might be a good candidate to consider. The downside is that they are very heavy, even though they're made of magnesium. They are also not quite as compact as the wood cameras, but they are cheap, and unlike the wood cameras mentioned, they have full movements.
