I'm not a digi-scoper, but I do own the Raven scope. It's served me well, and it's pretty sharp at the low end of its magnification (the scope only comes with a 20-60x eyepiece).
I have definitely looked through superior scopes (at significantly superior $ amounts, of course).
I'm pretty sure that the objective lens and interior optics are above-average quality, but I have two areas of dissatisfaction with the eyepiece:
1. The quality of image at high magnification (40-60x) is poor. I believe that the scope would be best served by a fixed 30 to 35x wide angle eyepiece. I have notified Eagle Optics of my preference, but get the idea that they're not going to offer other eyepieces for this model.
2. The exit pupil is very small at high magnification. This, along with the optical quality, makes for unsatisfactory viewing when zoomed in.
In defense of the scope, however, I will say that these gripes are indicative of compromises EO has had to make in order to sell the scope at the current price (I was not able to take advantage of the rebate, as it was not issued until after I'd purchased the scope - my fault for believing in the product upon its release into the market).
This is the trade-off: an economical scope will have flaws. I chose to purchase this scope because it was a marked improvement over the Bushnell Spacemaster II I had been using.
If I am ever in a position to purchase a Swarovski, Leica, or Zeiss scope, I will, but until then the EO fills a real need. Its quality is perfectly fine for much of my use, and I have money left in my wallet for travel.
