I ordered an angled Zen-Ray Sedona spotter from SWFA, but was unable to check it out because the hole in the mounting base that secures it to a tripod was incorrectly cut and it wouldn't mount. I returned it for refund and bought a Vortex Skyline 80 (non-ED) locally, but it had such heavy chromatic aberration I registered my concerns with Vortex Optics, who was kind enough to send me the ED version of the Skyline 80 to check out and see if I wanted to go in that direction.
Unfortunately, the Skyline 80 ED Vortex sent me was from their "demo B" inventory (if that was demo B, I would hate to see demo C) and was in such shape that I didn't even take it to the range. But I did compare it out my bedroom window to the non-ED Skyline while I still had both, and the CA was somewhat less but still evident in the ED version.
So I went from a <200$ spotter tainted with poor quality control (the Zen-Ray) to a $450 spotter that was not satisfactory for my needs (to see .223 holes in a Shoot-N-C target at 200 yards) to a $750 ED-class spotter that looked to me like it hadn't held up very well. I am at present spotterless, but hopefully a little wiser. You really do get what you pay for. I wasn't completely sold on that concept, but I am now.
One other thing: my experience was that any 80mm spotting scope will require a very sturdy tripod, so there's a few more pounds to carry around.
