Don't have the 10's but do the 8.5's and they are fantastic. I went back and forth between the Leica's and Swaro's and ended up getting the 8.5-42 Swaro EL.
I have heard really good things about the Vortex bino's and I just ordered the 15-56 Vortex Kaibab. They will be here Saturday so I'll report something back this weekend.
Doug at Camera Land felt pretty strongly that I would be happy and I know I'm VERY happy with the price as compared to the Swaro 15-56.
Also, don't forget to mention LRH when you buy from Camera Land. Being a LRH member will get you a pretty good discount.
