I've used a 1-4 before and liked having it. I want to get something decent now rather than something meh only to want to replace it later.
Then I would skip the primary arms and the Optisan. Spring for the Leupold. If not, the bushnell is nice but heavy. If you don't have to have the he illuminated reticle, the non-illuminated version of that 1-4x Bushnell is $99.99 w/free shipping at PSA.

i'm sure you could easily get your miney back if you decided to upgrade later. I'm really tempted to get one for a later build.
