If it's in excellent condition, without the corners and pointy head banged up, then he probably wants around $300 based on the new ones he sees at the big box stores (like the cheap Jackson V's and such ilk, which are around that price). That's if he's an informed seller. If it's in excellent condition and he knows what he has, then he'll want $350 or more based on recent EvilBay outcomes. Remember that you're going to have to pay shipping, which'll run ya anywhere from $30 to $60 most likely, so offer him $240 just to see what he says. He'll probably try to run the price up. And you'll probably have to follow up with him. Since he's one of those "make me an offer" kind of guys, he may sit on his offers in hopes to get more. So bug him about it. If you're looking to get a near mint old Westie, you'll have to spring quick when you find one as you don't find them very often at all, buy you already know that! Be sure to get close up pics first, especially of the pointy head and body. If it's banged up, but not too badly, offer him $200. Happy hunting Ice!
