I have a couple from Bradley and they are nice knives.
BTW, and perhaps you're aware, watch out for ones that are Philippine in style because the cutting edge will be reversed from what you might be used to handling.
Benchmades are the best you will find short of custom made balisongs. There are many custom balisong makers but you will pay a hefty price on them.
Unfortunately, there are really no middle of the road quality priced bali's. They are either high end or cheap chinese.
The Bradley Kimuras were a GREAT line! Pricewise and for quality. Sadly, they are not being made anymore. Spyderco had a couple but again, I dont believe they make them anymore.
Look at Microtech, Bladerunner Systems (BRS), and the Bear OPS line.
Have an older T-latch BM42, but my BM51 is smoother, and a little easier to flip, it actually makes a good EDC, very versatile and good for the money, zen pins are awesome. Not a fan of the 60 series Benchmades, the handles are too heavy, a big step back from the 40 series unless you spring for flytanium scales. The Microtech Tachyon is a nice knife, handles are a little plain, but flips well, and well made. The BRS knives are nice, but big, handled a few, the Replicant is a bit lighter than the barebones and beast, felt the best to me. I want to handle a Brous B3, looks cool, has a clip(I like to carry my Balis), and looks to be a good weight, stainless handles, but milled out a lot so they should balance
