I think the cascades are one of the better offerings (in 07 leupold/wind riverfleet anyways). However for less money I'd at least comparethem to the Nikon ATB Monarchs(like most Nikons they provide a feeling of a bright image, however the 8x monarchs hold their own in other areas as well...pretty darn good bin considering the investment). They come with a 25 year/no fault warranty.
I have also been impressed with Vortex.I admit to only having looked through their mid and upper class thus far but have heard good things about their entire lineup. Also might be worth consideration.
What ever you do don't buy without trying as many as you can stand...don't be in a rush either. I find comparing optics is like picking out a perfume for your wife or GF, if you try to cram to many into one session they end up all smelling similar and you may end up with one you never intended too. On both accounts I learned the hard way
