Hi. I have been looking at the TIE Intercepter, Set 7181, and the market value, according to BP, if I understand it correctly is about $375 new and $150 used. However, when I got to Amazon to buy it, the selling price is $799, and when I go to e-bay, the lowest value is $500. My question is: Where does BP get there values from, and what good is their evaluations if you can not get it for that price? This is NOT a criticism.....I am a newbie here and am just trying to learn how to buy, what to buy, when to buy and what price to pay. Grandpa
