My suggestion would be to buy used and go with Swarovski, Leica, Zeiss or newer Leupys. The high end Nikons are great as well as the high end Minox (the mid range minox are junk). The newer Leupold Gold Rings are about the best buy I have found/used especially with the euro exchange these days. If you are going to have your eyes in the glass for hours like we do in the west, you will get fatigue unless you buy quality. Use them on a tripod as well, big dif. If you are just lifting to your eyes to check out objects and not searching for hours such as heavy timber stalking then a mid range set is probably just fine. You will have these for ever and appreciate and use a great pair so dont skimp. I spend hours behind glass every year and every "bargain" set I have purchased has eventually disapointed.
Also you cant hold the 12s very long with out a tripod so stick with the 10 or less power.
