Old bass player friend of mine had a very nice Sadowsky J bass in a natural wood finish. Think he imported it from the US though so not sure how easy they are to get here – a quick Google looks like there’s a few about and in the price range. Could be worth a sniff.
Sadowsky entered into a deal with Warwick and the ones around £1.5k would be Chinese-built – apparently with very mixed reviews as to quality. You might just scratch a Japanese 2nd hand for that money though.
Warwicks hare great, but so SO expensive new now.
If you want a traditional style bass then as suggested above G&L are worth a look – the Tribute models are fantastic bang for your buck and the USA models stand up there with the best in terms of quality.
Don’t know where you are in the country but if you’re anywhere near the Midlands, a trip to Bass Direct should be on your radar…
