I love this site!

Especially these links, helpful for choosing eyepieces:
Choosing Telescope Eyepieces By Focal Length
Choosing Telescope Eyepieces By Manufacturer Series
Choosing Telescope Eyepieces By Price
These don't just link to information but to their actual catalog with prices ($US). Of course, they don't stock all brands, but they do have a lot! Postage is reasonable for a single item, and a doddle for multiple items!
Apologies if this is old news
