I have a Tele Vue Powermate 2.5X for sale. I bought it new in February and have only used it a half dozen times, if that. It's very nice, but I don't use it enough to justify keeping it. Besides a handful of small barrel marks where the locking screw held it in place, it's just as I received it.
The first $140 gets it shipped and insured USPS Priority Mail anywhere in the Continental United States.
For details see Tele Vue's web site.
I'll accept PayPal if you add 3.5% to the price otherwise send me a US Postal Service Money Order.
