My issues though is funds.

From my research, I see I can get a quality AR for $800 and up. I have read to stay away from Olympic Arms as well. It looks as though I could save money is I were to build my own and I see there are kits available online (such as http://www.del-ton.com/Rifle_Kit_p/rkt102.htm" onclick="window.open(this.href);return false;) . If I were to buy something like that, would I just then need a complete lower receiver? (http://www.del-ton.com/Del_Ton_Lower_Re ... /lr101.htm" onclick="window.open(this.href);return false;)
Can anyone lend any assistance as to where my best avenue of approach may be? Build or buy? New or used? Good places to check out?
Thanks in advance!
