Godin SD if you need the p/j..
Peavey Dyna (VFL Pickups) if you're looking for a higher quality bass.
Both of these shoujld be under $300.

How about a bass which sounds different than your current instrument?
A fretless wearing flats, or a five-string bass would allow you to explore new playing/music styles.
i just love pj basses. having the availability of two different pickups allows you to easily switch from a punchy tone to a smooth one. as i look at it, i want my first 2 basses to be ones that i am most comfortable with, that i would be playing the most often. maybe for a third, that would be a fretless or a 5/6 string.
i do have a traben (though i plan to sell it), but the frets feel just barely spaced further, and i just cant play as fast on it as i like.
also, i have looked over my budget, and i think i can push to getting something in the $400-500 range.
