Tons of great 2-stage triggers out there, some cheaper,some more expensive. Question is, what kind of quality are you looking for?
You'll never beat a Geissele, ever. Many come close, and there are many alternatives, at lower price points.
You'll never beat a LaRue MBT2S, at it's price point - no matter what you try to buy. You might wait for it, though, for months. I think it's still on sale for $99.
That LaRue is directly comparable with a Geissele SSA trigger, and the Geissele SSA-E is a little better - but that's an additional $100, minimum, just for the SSA.
We can talk triggers for hours, man. I've pretty much bought them all, over time - and still have them all, after all this time.
