I really didn't like my Squier Affinity Jazz. It had sharp frets, tuners made of cheese and I could just never get it to play nicely. Without doubt the worst bass Ive owned.
Id recommend looking for a used Ibanez SR305. You'll easily find one in budget and they're not just good for the price, they're just really good. They're light, comfortable, nice narrow neck and a big range of available tones.
Peavey International V is also excellent but not too common. Surprisingly nice bass and I managed to find one for £150
