I have a Squier P-bass and it sucks. Yeah, sure for a beginners bass it's not bad but it's a pain in the ass. The input jack is crap and the pickguard doesn't stay down in parts. If you are absolutely, positively 100% sure that you want to go places as a bassist then don't be afraid to spend a bit more and splurge for a more intermediate bass, but if your funds are low and/or you're not sure about being a bassist, or you don't want to wait or whatever, then do as you see fit. The squier I have is 4 years old mind you, so it wasn't always junk. I haven't exactly worked with very many basses though so the Squier I have is all I can go by and it cost me about $130. Just remember, you get what you pay for.
