I think that Cabelas (online) has a pretty crappy selection of traditionals.
In terms of straight up function and sticking within your price range, sticking with a traditional and what I just saw scrolling through Cabela's offering of folders, I would have to suggest looking at the following:
1) Buck 55. It's made in the US. Buck's 420HC is a good stainless if you want stainless. Classic looks. On the downside, I don't care for clip blades for EDC use and I find the 55's blade on the short side for food prep. But, the blade locks which I find helpful for things like box cutting and pumpkins.
2) Uncle Henry Bruin. This is a very painful suggestion for me to make. I have an original made in the USA Schrade 5OT Bruin in my pocket as I write this. The blade is a very useful drop point and it's just long enough to be useable for food prep. The frame is nice and thin and it pockets wonderfully. The current Old Timer 5OTs and the Uncle Henry Bruins (close twins) are made in China and have generic 400 series stainless. I love the pattern but don't like the current execution. Very sad knife to my eyes. If Cabelas stocked the Buck 501, I would suggest that instead. Made in the US with better 420HC steel.
3) Case Mini Copperlock. This is just a tick out of your $50 limit. There also a bunch of Case slipjoints in your price range.
Hope this helps. Note, I've very biased towards locking blades.
Last, last note... Cabelas does have the Buck 110 for around $40. It's a best of a knife and will destroy boxes, pumpkins and the bottom of your jeans pockets with ease. By far, it's the most knife for the money that they have in a tradition. I find it to be too much for EDC use but am very, very glad I own one.
