Farmboy,
I know you want to stay within a budget however if there is any way for you to make it work you will be money ahead and much happier if you figure out a way to buy a pair of Leica Ultravids. The Swaros and Zeiss are good too but my experience is with the Leica's
You will probably own and use them the rest of your life and the resale value on them is real good in the case you want to upgrade (if such a thing is made) in the future or sell. The purchase price in the beginning is tough to swallow.
Have had the pair I carry since Leica came out with the Ultravid. Still have a pair of Leupolds and a pair of Steiners both of which are good glass but...
If you can make it happen you will never regret it IMHO.
