I'm thinking of buying Polaroid's Sprintscan 120 film scanner so as 
to be able to scan my 35 & 120 film.  I notice that the 35-APS 
version has now dropped to around $500, which is very attractive, as 
most of my film is 35 mm.  I'm currently printing on an Epson 1160, 
Piezography CIS, and HP Photosmart S20 film scanner (2400 dpi max, 8 
or 16 bit).  

I know that this is a personal decision (when to buy), but I'm 
wondering if I should buy the 35mm -APS version, and wait for the 120 
version( by Polaroid or others), also to drop significantly in 
price.  Maybe someone has some information that would signal a wait 
on the 120?  

I also think I read somewhere the Sprintscan 120 is a slightly better 
scanner (quality wise) than the Sprintscan 35-APS, but I don't recall 
why; any truth to this?

Most important, if anyone has the 120, I'd be interested in finding 
out how they like it, and if they have had any problems with it on a 
Windows 98 system?  

It also looks like I will have to order my purchase over the 
Internet.  I've seen recent mention of Ecost.com, for a low price.  
Anybody have any bad experience ordering a film scanner from a 
specific company on the Internet?

And finally, are there other 120 format choices out that in the same 
price range that might be a better choice?

Any thoughts on this matter would be appreciated.
