Thanks for the advice. You too, Baatar. My budget at the moment would be at the most around $400 if I dig deep into my pockets T.T
*sigh* how the hell did I come up with starting a hobby that is so expensive haha

You might as well save up for a DSLR with that budget. ;D If you buy refurbished or used, you can easily get a D40 body for ~$250 and the kit lens for less than $200.
But, since I love film and think everyone should shoot it, here's my real recommendation, haha. I like manual cameras so most of these you'll have to do everything yourself, like focusing and setting aperture and shutter speed (awesome practice!) I suggest starting off with a 50mm prime (f/1.8 of f/2). Instead of zooming you have to move your body to compose the shot.
Nikon FM or FE: These things are solid metal. The FM is my favorite of the two, and is completely manual. The FE has auto-exposure and exposure compensation. They both can use pretty much every single Nikon lens except for the G series. They tend to go for $100 ~ $200 without lenses. HOWEVER, with patience and obsessive craigslist/ebay stalking you can find good deals. I paid less than $45 for the FE and only $30 for the FM.
If you want autofocus, I think most of the autofocus Nikon bodies are good and not that different unless it's a pro body. Mine was a N75, and you can get it for about $60 these days. Also good are the N80 and N90, both of which are around the same price.
Pentax Spotmatic: This is a classic camera (also manual). It uses screwmount lenses, which are very versatile and work on many brands of cameras (which also means many brands of lenses to choose from). However, because this is a very old camera the light meters are sometime broken. Also, it was made to take mercury batteries so you have to find replacement ones. Bodies go for around $100.
Canon AE-1: Another classic camera (manual). Canon changed lens mounts so you can't use modern Canon lenses on it, but the lenses for this camera can be found very cheap. Goes for about $50 ~ $100, lenses are often included. This camera constantly pops up on craigslist.
Olympus OM10 is another very popular film SLR, but to be honest I don't know much about it. Goes for around $50 body only.
Most lenses, especially the basic 50mm lens, can be found for these cameras for around $100 or less.
