EBay prices vary, of course. I've not seen it listed at Tales of Wonder. Places I've seen it online and in stock are Stuart Ng (they initially listed it at $125, then changed it to $150), Bud Plant $150, Midtown ($125 list, $106.25 on sale), In Stock Trades ($100 list, $95 after discount!).

The Diamond shipping list had the price as "AR," for "Ask your Retailer."
