I am usually not a great advocate of Tasco products, however, I have an older Japanese made, EXP series, 10 X 42 power binos.
I bought these from a good friend, and sporting goods dealer in Cold Lake.
I have never regretted the purchase, but these of the current Tasco (World Class?) line, are made in China and South Korea now. Not of the same quality.
If I had the money to burn, a Kahles set of binos, would be my first pick.
If not, the BSA Monarch series of binos, (yes they make 10 X 42) was one of the lesser priced options, I once looked seriously at.(500'ish)
EDIT: I just did a google search, and the Nikon Monarch ATB 12x42, look like good quality, for the money.
But I would check out on-line reviews first off.
