You didn't say whether you already have a computer, but any Mac with a DVD burner would do the trick. Macs come with iMovie and iDVD, which, if you haven't used them before, do great things with home movies. You'd also need a digital camcorder, which I assume you have if you have your movies on DV, to transfer the movies via firewire to the Mac. You may also need a firewire cable, but I believe most camcorders come with the right cable (mine did anyway), and would only be a few bucks at an electronics store if you don't have it.
To get VHS into the Mac, what I've always done is just record the TV to the digital camcorder and then transfer that to the computer, but there are dedicated devices that do that sort of thing if you do it a lot.
