The point to examine Buster, is the avalibility of replacements. I don't have a Colt. I don't want a post ban Colt. My only solution has been purchasing a preban at the the price the market dictates. Now fast forward a year. I want a Colt with proper the configuration. You are selling a Preban SP1 for $1200. Eddie's Guns is selling a NIB 2004 manufacture configured the same way for $950. Why in the hell would I buy yours, even for the same price?
Example 2. I have a pre-ban Sporter & a Gov't Carbine. Enter my typical need for $$$ (Suzy's braces, a once in a lifetime Harley opportunity, Credit Card debt ,etc). I try to sell the sporter for $1400, No bites. $1200? Nothing. I NEED$$$!!! $1,000? I get an offer for 700! I am about to eat a razor blade for this... but I have to sell the Gov't carbine then. 2,500? nope, 2,250? no bites most people out of $ buying new stuff. I would probably have to sell for $1,800 or less EVEN THOUGH IT IS WORTH MORE.
The bottom line is that most people sell from a need to do so. If you refuse to take a beating on your $1600 preban you'll say it's not worth selling. But if you need the money you will have to do what the market dictates and right now, or particularly post 04, the market is going to slaughter those kind of Colts.
