I've had my ME Super for a few years now and this year I picked up a K1000 dirt cheap ($5 equivalent). My first SLR was a K1000 back in the early 80's so I bought one again for sentimental reasons.
I tend to use the ME Super most because of its smaller size means it fits nicely in a large pocket but its biggest drawback for me is the max asa of 1600. I like shooting low light stuff at 3200. Well tonight I was fiddling with the asa dial on the K1000 and I noticed that it went to 3200.
I had just assumed that as the K1000 is the older design, the max asa would not be any higher than the ME Super. Its a pleasant surprise that means the K1000 is going to get more use in the future
