Free or close to it would be a good starting point. Assuming you have the room, you might look at picking up a Beseler (or similar) 4X5 in case you decide on 6X9 or 4X5 format. Your best bet is to watch for someone who has the associated equipment you will need in the package. UNless free, I'd probably only look for a package which includes the lenses and negative carrier. You will likely end up spending more for those pieces if bought seperately than you would for a complete unit. Bill Barber
