I've used an NC2 that has broken/separated glass for about 5 years (it was $19!). I'm feeling like I deserve a finder with complete glass. I wear glasses, but hate diopters so I need good eye relief. I've heard that the latest PM45 is great....and quite expensive. I'd be happy with a "new" NC2, but are any of the more modern prisms better and usable with glasses?
Depends on what you consider expensive but the older incarnations of the pm45 aren't so dear, I've not paid more than $100.00. They work fine with glasses, though you may want to switch from the standard eyecup to the rubber ring on the eyepiece.
They are a bit lighter than the NC2, at least it seems so, (I've never measured), and slightly more compact, if that helps you justify the expense.
