Hold on...You found that the MK-52 is better than the MK-61?
I have only experience with the MK-52 and didn't think its construction / build was all that great.
I guess I should really avoid the MK-61!

I will say, I think part of the appeal of these is the Cyrillic letters. A picture of a translated keyboard to reference (for a while until I get fluent) would be great, but I don't think I want to cover up one of its few charms. :-)

Yes in my case. I am sure it depends a lot on the manufacturing date, what the guys on the assembly line were drinking that day etc. In my case my MK-61 does not want to turn on, the keys are like the teeth of a 150 year old pipesmoker, etc.

The MK-52s I got (two, one I gave as a gift) were in much better shape, the keys are all standing tall and the sponge seems to give them relatively even pressure, and they turn on and function without begging and pleading. Many people here read Russian so I'll have help from friends and coworkers. The main thing for me was to know where the Enter key was. Thank you, Jebem!

For me the appeal was finding something made somewhat close by (many people still remember Czechoslovakia under the communists) and that uses RPN. And the MK-52 is supposed to be unusual because of the PROM memory, modules, etc. Too bad the construction is so shoddy. Anyway they come with schematics unlike most other calculators. So they should be repairable

I have an MK-54 coming soon. I'll report on that when I get it and post a few pics of the trio.
