Yeah but there is a market for ua-5's, modded or unmodded. Bottom fell out of the dat market.
edit to add:
What I mean is, doesn't matter what the d7 is worth, you will never get it because there is no demand. Hence, you must sell below est. value of the deck. There is a market for ua-5's, so one would be able to get an est. value of the ua-5 in a sale. So back to the original question, what is the bm2p+ worth? Personally, I think the $400 mark is a legitimate estimate. Just my $.02
