I just got back from the local camera shop after purchasing some new binos
Checked out about 8 sets and like you Im in hte low end of the price range
Checked out quite a few Tasco, Bushnell and 1 Leica and some other one I cant remember now
Basically they were all a bit ordinary, lots of dispersed light, ordinary to poor focus and this includes the Leica which clocked in at some $750. Actually I found that one the hardest to use overall, stiff and not useer freindly controls, OK focus point, OK low light.
Then I was handed a set of Pentax and they were an immediate standout, sharp and fast focus great field of view, really sharp and colourful, pulled into the dark spots well, great to handle.
They were an 8 x 40 WPII, Nitrogen filled and they cost $350 and I didnt shop around for a better price
I wear glasses so eye relief and ease of viewing was really important to me as I just cant take specs off every time I want to glass like I had to with my cheapies.
I watched a wattle bird at about 100m today in medium light conditions and I reckon with a bit of time could have given a positive ID on his breed. Colours were nice and clear, easy to pick him up and even hold the glasses with one hand
