Spector make excellent entry level basses... but regardless, does it feel good, play well & sound good to you? If so, that's all you need to make the decision
I'd try to bring it down to £150 though if it is used and has some scuffs.
Alternatively, if you're willing to save a little more I'd go for a Spector Legend bass, or for a little more again a Spector Re-Bop! Both excellent value for money basses....
