You don't even need stabilization/vibration reduction, you just need a faster shutter speed (and/or better light/light sensitivity). VR/IS/whatever the company calls it can help, but if you can set exposure to 1/125 or 1/250, that should be fast enough to negate the tremors. If it isn't, bump up the ISO setting and open your aperture as wide a possible, then set it to a faster speed - if that is still too slow, you can look at getting faster lenses (lower aperture) or adding more like with a flash, reflector, or studio lighting.
When you are using a tripod, use a remote shutter to eliminate vibration completely (even if you didn't have tremors, a remote shutter is still a good idea when you're using a tripod).
You can get cheap used or refurbished DLSRs online, but if you're using a film camera, another thing that will help you is switching to a higher speed film (try at least 400 ISO). If you're on a budget, look at used prime lenses - they'll have a very wide aperture for not a lot of money. They are available for film and digital cameras alike!
Sorry to hear about your tremors and I hope this advice was helpful, keep shooting! I think you'll find having a remote shutter or release makes a big difference. If you have an old film camera, it most likely has a mechanical shutter release. If you aren't sure, post the camera model and one of us can probably help you find something.
