Value of a TTA cross drilled crank

[Steve]

I have a std/std TTA cross drilled crank that I am thinking about selling and I haven't seen one sell for a good while so I wanted to get some opinions on the value. I am going to take it by a machine shop and get it polished so it will std/std, polished and ready to drop in. The crank was bought new from a GM dealer in the mid 90's when they were still available. The crank has about 2k miles on it and very fun runs. I think it's worth a little more than a normal high mileage turbo Buick crank but I know it's not made of gold! What do you guys thinking a fair price is for the crank?
