yep, what ever they cost will be down the drain. never go below 30 mm objectives. And that is not that big. I have a pair of Steiner 8x30 predators. Fairly light but not small. 30, 32 or 40, 42 mm are better. I think mine are good for the money ($189). Nikon has a 8x42 that looks interesting.
If you have very little to spend, get cheap-o 8/10x50. The cheap ones are really light which helps make up for the size. the 50mm will pass more light.
Trust those guys, the 21 or 25 mm you will hate the last hour of the evening.
They ain' t cheap. sorry.
If you have to buy Walmart cheap, look at the 8X32 or 10x32. I don' t like anything above 8x. If you want to get me something for my birthday, I want 8x42 Steiner Predator. Can' t swing the cash.
Edit: Look at these simmons 8x42 for 49.99 at nachez. I order from them, they are good to deal with.
