I have a chance to buy a 2015 4003S for around $1,200, owned by a keyboard player that bought it new and never got around to learning bass. I'll get to see it and play it for the first time tomorrow. Based on other threads here, I am hoping I could get a new 4003 for around $1,500-1,600 if I am patient and shop around. I have never played a Rick and at $2,000, have just assumed that they are out of reach. At $1,500-1,600 for a new 4003, I am wondering if I will regret buying the 4003S used. For those of you that have owned both, would you regret buying a used mint 4003S if you could afford a new 4003? Thanks!
