To the OP, unless you are planning on going to war with the weapon, there really isn't anything a $2k gun will do that $750 gun won't, and even then you'd probably be dead before you found out what that is. The market is so competitive and tight right now, yet most of the big names are still asking a premium for their guns when in all reality they aren't much if any better than the competitor. Buy what you want, just remember the gun doesn't make the operator better.
Sorry to hear of your health problems J, you've been around as long as I can remember. Have you considered listing it on the ODT since you're in Ga? It's probably the largest private firearms board in the US. I've bought/traded/sold almost every gun through there over the past 8.5 years since it's inception.
ODT? Please tell this old dummy what that is.
