I have a zx30 that I got not too long ago. It's autofocus, but it's really simple to use. As for how the pictures turn out with it, I can't say until I take the first roll to get developed tomorrow. I got it for under $40 on eBay, including shipping. I saw the same camera at my local camera store for $199.
To answer your question on whether or not your lenses would fit, all of them will fit, but lenses designed for "full-frame" cameras (24x36 exposure area) are the ones you need for a film SLR. A lot of the newer lenses are designed for "digital-only", meaning that they're designed for the smaller APS-C digital sensors. Full-frame lenses will work fine on a DSLR, but if you try to use "digital-only" lenses on a film SLR, then you'll get major vigenetting.
Also, which full-frame lenses you would use on your film SLR would depend on the type of body you get. Autofocus bodies will take both autofocus and manual lenses, but your options are more limited with a manual body (I've never tried using a autofocus lens in manual focus on a manual focus, so I'm not 100% positive on that one). I started out with a manual focus film body, but missed autofocus so much that I opted to sell that body and pick up a AF body.
Picking up the film body changed the way I look at building my lens collection. I just got rid of my Tammy 18-250--not being able to use it on my film SLR being part of the reason. Now, when I'm selecting lenses, I'm going for full-frame, so I can use them on both bodies. I'm also hoping that one day Pentax will come out with a full-frame DSLR, in which case I'll be ready.
HTH,
