A few years ago isn't today and the market is no where near the same. $200 for a Ricoh 6X6 is way to much IMO.
$300 will buy a 645 or even some 6X7 cameras with a little shopping around. Tell you friend that two years ago a Hassleblad was $600+ & now you can find them for less than $400.
See if he'll take $100, if not, shop around.
