When you say tight budget, about how tight? My runaway favorite for a non-liner/frame lock knife is a Spyderco Chaparral; it clocks in at around $100, but it's unbelievable nice. The fit and finish on the Taichung Spydercos is impeccable, CTS-XHP is an excellent steel, and it has very thin blade stock, making it an incredible slicer and very thin in pocket. Plus I like the look of the CF/G-10 laminate.
If that's out of your price range, there's always the Delica, which is a solid value, but I'd go for the Centofante 3, which is a criminally underrated knife. It's the same price as the Delica at around $60, runs the same materials, has a slightly longer blade, and I personally prefer the aesthetics of the Centofante. The Delica does come in different colors, I suppose.
