Getting really hard to source a used 25-50 anymore.
I have a 30xw here at the 'RS classifieds that I'm going to be popping back into the safe, but before I do, I'd suggest you consider it.
For a mere fraction of the cost of the increasingly rare and increasingly expensive (even pre-owned) 25-50 you'll be blown away at the difference between the 30x and the 20-60. 27-32X is the sweet spot of the 25-50 anyway.
Just a thought.
I don't have much use for Europeans overall, but they have figured things out optically, the fixed eyepieces are very popular there for good reason.
