How Much should I spend?

[IbanezPrestigeBoy]

A friend of mine showed me a guitar he had laying around. It was a Transblue quilted top Ibanez s-540 in Absolute Mint condition. He is a real hardcore Gibson/Fender guy. It's really nice, and I haven't seen one in that blue quilted top before. My question is how much should I pay? He wants $650 for the guitar with the HSC and the trem bar along with the tools.What I really like about this guitar is that the neck feels like my '89 570 but the body feels like my s2120xav. It's a combination of my favorite aspects of my other two guitars!
Can any of you guys give me an idea of how much this guitar is worth?
Thanks for lettin

$650 is a bit on the high side for an S540FM, but...it's worth whatever you're willing to pay. I got my S540FM-TP about a year ago for $400, and it was also dead mint
