With all the fine choices from TeleVue in the 20mm range (18mm Radian, 19mm/22mm/24mm Panoptics, etc.) it just doesn't make any sense at all not to sell me your 20mm TeleVue plossl and buy something else for yourself.
...Okay, maybe that's a little one-sided ;^)...
Nevertheless, I would REALLY like to buy your 20mm TV Plossl (hint hint). I just found a 32mm with a smooth barrel and a rubber eyecup in excellent condition--it would be nice to have a 20mm to match, but I'll take pretty much anything you've got as long as the glass is pristine and the views typical Televue.
Make my day! Send me your best price for your 20mm insured/shipped to 84102 in Salt Lake City!
