My buddy has three of them, dhall, they are good bikes and highly collectable. I too like the styling, was admiring a nicely restored one at a bike show last year.
However, there would be one thing we would not like: the big twins do not run as smooth as our SOHC Hondas, they tend to vibrate a lot.
I feel at $2500 they would be a good buy if in good running cond, would sell around here in the $4K range if you could find one (currently none on my local CL).
I suggest you go for a test ride....
