I bought a second M8.2 this year instead of buying a couple of M9s, which I could have afforded. I posted elsewhere why this works better for me, but in a nutshell...
Got used to the crop in no time despite 3 decades with film Ms. Put on filters once; never touched them again. Prefer using 2 cameras with 28 Summicron asph on one and 50 Summilux asph on the other, rather than switching to full frame and having to use my 35 Summicron asph (not as good as my 28) and 75 Summicron asph (don't like the 75 frame lines and the 50 is special) for similar FOV.
More clarity of files right out of the camera than the M9 due to less filtration, which also helps with b/w (and IR, but I don't use it). Comes in chrome and has a sapphire screen, unlike the stock M9. Has a marginally quieter shutter than the M9s I tested at a dealer shop (nothing significant, but 4 people including the Leica rep agreed).
The 2m frame lines on the M8.2 are also the best I've ever used (for my shooting distances) on any M. I think it was a mistake to go to 1m on the M9.
And most importantly, my prints look terrific as is, as I don't print huge sizes. I also don't shoot extra wide, so this is no limitation for me; nor do I shoot extremely high ISO (ASA 400 was high enough in my film days).
Oh, and I like the black dot on the black camera.
No reason I shouldn't get many more years out of these cameras, with Leica support as needed. The first one (black) I bought new; the second one (chrome) I bought mint used and similar cameras are selling for as much or more than I paid. There will always be fewer M8.2s than M8s or M9s, although one could argue that this is irrelevant value-wise in the digital realm.
Guess you can tell I like the M8.2. I think it's a fantastic camera and better sorted than the M8; I have had no problems with either one, which is more than early M9 owners can say.
By the way, the $2500-$3000 you quote is generally what people want for the M8, or partially upgraded M8, not for the M8.2. That's a great price, but I would only buy from a dealer with warranty.
