Hmm, that's too bad, but six rolls is probably enough to make that call.
Maybe you should consider a more modern RF, not just SLRs? You can pick up fixed lens cameras for very little money. My first recommendation would be a Vitomatic, or you can trade in build quality for features and get a more recent Japanese one. There's a thread around here about the "best" $50 Ebay camera to get you started.
I agree with Mukul (payasam) et al. above that you may not be happier with an SLR if the problem is with your vision.
Whatever you decide, take your time to get a good price for the Leica kit. If it's in good shape and you weren't fleeced when you bought it, aim to get back what you paid.
