I'd personaly go with the a new 5'8" Schimmel -- I dont know what the finish is,, but Schimmel has a nice two tone (walnut/ebony high gloss) finish which is real nice.. I would not take my chances with the restored Hamlin,, if you have the option,, go new..
as far as new vs. vintage,, in my opinion its all preference -- new pianos have alot of new features,, patents etc.. -- old ones sound all nice and broken in..
its a matter of you going out there and doing some ground work,, play on some old restored/original pianos and then try out some brand new ones,, see for youself..
