With a budget, you have the ability to go to a custom maker like ray laconico and get something very nice and clean that is as thin as you want it, just the right size, steel of your choice, and other things like this. you probably could not get a s90v balisong for the price, but a basic fixed blade would probably be very doable. besides, you get something that you like, not something that you live with.
The knife would be used primarily for general utility. I carry a handgun for self defense, and state law prohibits carrying a blade for purposes other than a tool, so it shouldn't be an obviously weapon oriented design (i.e. double edge daggers, etched with combat oriented names/logos, etc).
For utility uses, I prefer a thin blade which slices better. I hate all the smallish knives out there made from 1/4" stock.
The ESEE-3 and Street Beat appeal to me, though I wouldn't mind something with nicely figured wood scales either.
Production or custom, carbon or stainless, either are good. I don't NEED to spend a lot, but up to around $250 is doable.
Since your budget is up to $250 I'd suggest checking out the For Sale: Fixed Blades section on here and looking at the work from various makers. Find one whose work you like and shoot him an email.
