OK now you have given us some specifics. You need a good quality 8X or at most 10X glass. Any more and you are fighting a losing battle as you cannot hold them steady enough for clear viewing.
I guarantee you that you will see more detail with a good 8x than an average 10x. And definitely way more than a mediocre 12x when held in your hands. I spent a lot of time comparing glass over the last 7 years and in the process got quite an education.
You can file any statement that "my $200 glass is a clear as a $2000 glass" under the file labeled "horsedip". Kind of like saying my Cobalt rides as good as a Cadillac - Sorry ain't happening.
What you CAN do is get a mid price glass that comes close to the top shelf glass, but if you look real hard at the fine details, resolution, color rendition, sharpness at the edge of the field, etc, there IS a difference. If it is worth the almost 2 times the cost is something you will have to decide.
I chose to buy the BEST glass I could afford and figure it as a longterm investment. If you are willing to spend say $800 you can get some very good glasses. On my 8x glasses I spent the money for the "alpha" glass as I use these the most, Leica Ultravid HD's. For 10x I went with Pentax DCF ED's, VERY nice, ALMOST alpha. I do not use the 12x a lot, and for that I went with the Meopta, again VERY good but they are not a Leica or Swarovski.
Once you use a GOOD set of glasses you see pretty quick the differences in what your dollar is buying. Sorry here but the top name glass rules, there are good lower cost alternatives, but do not think for one second that a $400 glass will rival the big guys that cost 4-5 times that.
