@photopuck fwiw, if you have some favorite old frames that're still in good shape, you can get better bang-for-buck by re-lensing them.

Not necessarily cheaper, but it allows you better-
quality glass for about the price of frames + generic glass elsewhere. This also opens up the options for lens coatings.

I'm thinking of doing this to get photograde lenses, since cheap PG is worse than useless and good PG is 💸💸💸

This site is interesting... there are others, too...
