Re: Leica R8 Serial No's ??
My R8 is a 2293xxx, so maybe I should start freaking out, eh!
However, no problems to date with it (the DMR has an R9 attached). At this stage of the game I would imagine that most cameras which had problems will have been sent back to Leica for repair or replacement, but if you are still concerned, then obviously the advice given in the link to seek out a later serial number is reasonable. I think Leica are pretty reasonable with sorting out an inherent problem (as opposed to one that develops from use/misuse). Earlier this year I sent a pre-aspheric 35mm Summilux-M for adjustment as it wouldn't focus to infinity on my M8. They could reasonably have levied a charge for the job, as there are plenty of alternatives in that focal length, but it was done F.O.C.
A few years back I did briefly own another R8 + winder. This had an intermittent problem of locking up, which I blamed - perhaps unfairly - on the winder, as there was no problem without it. My current body has the Motor Drive R8 mounted; that makes it fairly large (though a touch smaller than a Canon 1Ds FWIW), but the handling is superb as Peter has already alluded.
Regarding your consideration of the winder, this does have the advantage of using regular batteries IIRC, whereas the MD uses a proprietary rechargeable. That battery is now only obtainable new from Leica's service department. I bought three to go with the one god one that came with the drive (another that got thrown in with the deal turned out to be dead). If that were not an issue, I would recommend the drive over the winder anyday though.
As Peter says, buy from a dealer. If any problems arise then you do have the shop guarantee to get it fixed at their cost. Some dealers may not like your using that, but do so. It's what it's for after all.
