Man, I could send you an extra Pentax medium (2 1/2x3 1/2) to use for a week. You'd have to get film, because I need the digital back for the other unit.
I have a Russian copy of a Hassy...the whole system, actually...but never used it. It's 2 1/2" square.
Speaking of costs, I have lot's of guitars worth $10,000, $20,000.00; even some worth $100,000.00 or more. Arrangers are generally way less than collectible guitars.
The good news is, unlike keyboards, guitars gain in value if you know what to buy.
