Usually in the $200 to $300 range but there are some basses in that range that play and sound as good as more expensive basses. The Fender Precision and Jazz "Packs" are good for people just starting out because the basses are very playable and they come with an amp, gig bag, strap, cable, headphones, tuner and DVD.
