If you're simply testing the waters, I'd probably go the Cosina Voigtlander Bessa route. It's less outlay of cash, and they're reasonably easy to resell.
But it's probably the camera that will hold its value the least, unless you buy used. If you buy used, you won't lose much on the resale of a Cosina Voigtlander Bessa.
