Bob, I have a customer in NY, (near United Nations area.), I'm trying to close deal on. Originally I was jsut planning on buying a 100mbCogent link from a near buildings, and Tlink45ing to it, Since prospect needs 30mbps.
I saw you mentioned "Manhatten". Do you accept T&M wireless field service work? If so, what are your rates? I might as well ask... Do you wholesale Transit? PS. The last 300mbps Airpair 23Ghz w/2ft dishes, that I bought (this month), I paid $10,800 (with Hi-power) NEW. My Trango Apex w/ dish (same spec), I paid $8600 new (this month). $10,000 really isn't a steal anymore for used gear, if its a savy buyer. You were asking a "fair" price, but it was not a "steal".
