Where to buy Fast Fire 3? (and options)

[HoggleGobble]

Well, after reading many reviews on Eotech 512s, Aimpoint m1s, and FF3... I decided to go w/ a FF3 for my new SBE2 pistol grip. My question is where is the most reliable place to purchase w/ the quickest shipping? I may in fact buy 2, as my 870 Max gobbler needs a new red dot since my Speed Dot will not hold a zero.
Also, what options can I purchase to protect the FF3 from hitting limbs and other things and I walk through the woods? I'm pretty hard on my turkey guns. What rails do I need to purchase as well, picatinny? Thanks guys!!!

Optics Planet as mentioned.

As far as the mount...this is what I ended up with.

I've had to adjust every base or bolt for the Fast Fire mount.

Burris has a protector, and they run from $60 to $100, nice, $100 protector for a $200 sight....

If I mount it to the 336 weaver, do I need to purchase the FF3 w/ picatinny mount option? One is $239 and the other is $254... If I bought it w/out the picatinny mount option, how would anyone ever mount it??
