The $799 US Sig Extreme was a great deal. It's a hard to find 'up level' P226. If I were you, I'd ask in the IRG thread if anyone wants to sell theirs.
I love the 'no beavertail and no E2 grips' on this version but with the custom G10 grips and SRT. P226 is an awesome pistol in base form but this has some upgrades and other things that are really not needed (unless you like a beavertail that has no real purpose or have small hands).
