I think you can get the Hassy for less than $1000 if you look a bit harder. I'd go with that over the Rolleiflex just because there's more Hassy stuff around and you can upgrade lenses/bodies/backs/finders, if that appeals to you.
The Zeiss glass is attractive. I have a 135/3.5 Planar for my Linhof that's just outstanding. I thought for a moment--"trade the Bronica for a Hassy?"--then came to my senses and said--"and waste all that money on such a puny neg? Better to save up for a Sonnar and maybe a Biogon for the 4x5" kit!"
