ee parts = overpriced
Building a rifle from used parts should be an economical venture. But you get the guys on the ee who buy a bare bones rifle for $1400, use it and then try to part it out for for a profit? Selling $1000+ upper assemblies that are worth maybe $700-800 and $500 for a lower that is worth $300-400 at best. These things never get sold....they just clog up the ee, bump, bump, bump, bump, viewed thousands of times and get bumped every week forever......
Wait it out for the guys who sell at reasonable prices. I've seen frankinrincos being advertised for $1,600!!! Here's another one...buy a rinco <$1000, shoot it up, sell the lower for $350 and the upper for $800 and profit yourself $100.....you have no shame! Many <$100 parts can be purchased new at Brownells for less than they are advertised on the ee as used.
Do your homework before you invest in the ee.
