Went through the list of knives I own, looking for things $60 and less that I felt I would particularly recommend (excluding Kershaw, my favorite knife company, per your request) and I would recommend you check into the following...
Esee Izula 1 - This is a fixed blade, not a folder. I started out only interested in folders, but I have found that small fixed blades like this are pretty cool, and this one is very highly rated. $45-$55.
Spyderco Tenacious - I'm personally not a hugh fan of Sypderco genrally (other than the Paramilitary 2, which is out of your price range), only because I generally find the width of the blade with the Spyderhole is too wide in my pocket, but I have both the Dragonfly and Tenacious and although the Dragonfly has better steel, it is quite small, so I would recommend the Tenacious instead, very highly rated generally. $35-$45.
Ontario Rat 1 - Not a very 'sexy' looking knife, which stopped me from buying one for a long time, but feels EXCELLENT in the hand and the manual opening is EXCELLENT. Very highly rated generally and inexpensive enough to allow an additional purchase. $30-$35. Knifeworks.com has the best selection of these that I have seen, though it appears to be rapidly dwindling after I mentioned that in another thread.
SOG - Generally, I think their knives are a bit overpriced (though nowhere near as bad as Benchmade), but I seem to find I prefer SOG's for EDC. Two within your price range are the Flash I, which is quite small, but I believe it is definitely the best knife available in that size range, and the size makes it easy to carry without even knowing it is there (and no joke, I lost mine for a couple days, then found it was clipped to my pocket and I found I was clipping another knife next to it!). $32-$38. Another larger SOG option would be the Mini Aegis. $42-$53.
Chinese - Probably a controversial recommendation, but if you'd like to get a few knives, both Ganzo and Enlan Bee in China produce a number of very nice knives in the $20.00 range.
So... my post is probably not making your decision easier, but the research is part of the fun!
