Hello
I usually go for a good to great deal. I don't need anymore guns (least wife says so). But, I love every gun I have ever seen. So to keep both of us happy, I don't buy unless I find a steal. I usually make the rounds at the local dealers once a week. Occasionaly I find a real diamond. Recently I found a 1st gen. G17 with 2 hicaps, in really good condition for 260.00 OTD.
Sometimes I am bitten by the new gun bug and impulse buy. My last 2 were like that. Sig 220R ST and a Lew Horton SW1911 PD, but they were both reasonably priced. For AR's I just scout the gunboards for pieces one at a time.
Gun shows are the best way to find a deal if you have the cash in hand. Don't be affraid to haggle esp. if it's a used gun.
