I would recommend using a DSLR with a good, flat field macro lens and a light table over a flatbed scanner. I have a Epson 4990 and use it all the time for scanning film. But it's only really worth it for large format type stuff. For 35mm film, the quality just isn't worth the hassle. With 35mm, I still can't get a scan that's good enough to print from, at least not at a decent size. I get much better results by scanning my film using my DSLR, and it's a lot faster than using a flatbed scanner. If you don't want to go that route, then I'd recommend a good, dedicated 35mm film scanner. Flatbed scanners are great for larger formats where you have detail to spare. But for smaller formats like 35mm, they're not good for much more than posting photos online.
And you can still edit jpegs. I don't know why you think you can't. Photographers seem to get stuck on these hyperboles and repeat them ad nauseam without having any personal experience with the matter. I'm a graphic designer. I edit .jpegs all day, every day. Sure it's not ideal, and they're not as flexible as noncompressed files, but most of the time, they can work just fine if you know what you're doing. The only time you really need the noncompressed version of a file is if it's really poorly exposed and you need every last ounce of information just to try and save it. If it was a well exposed and scanned photo to begin with, you shouldn't notice a difference between an edited .jpeg and an edited .tiff. Not if you know what you're doing anyway.
