Nope.
I've not owned "cheap/beginner/average" gear since I was in my school band and buying gear from the money I made on Saturday and summer jobs. I believe we should always buy the best gear our budget can afford.
IMO the price is the least important part of an instrument. Find a good bass, one that feels and sounds better than your current bass, then if the price is right, buy it. I play all my gigs, whatever the money, with a couple of rrp £2500 - £3000 basses and I don't see anything odd or wrong in doing that. If my budget fell off a cliff I'd carry on with a Sire, Squier etc, but there's no bragging points in cheap or expensive basses. You just need to play the best one for you. The one that makes you sound as good as you can be.
