SWFA's SS 3-9 is $599 but would fit the bill nicely and is a really good way to get info FFP as it is tough as nails, has very repeatable turrets and has a pretty decent reticle to boot. On an '06 it is all the power you need for LR shooting IMO.
Also, don't forget a fixed power scope as an options too. You can learn the concepts of FFP but get into a scope for much cheaper. Bushnells 10x and SWFA has a bunch of them.
Also, the used section here and on the hide is a good place to find good used scopes for a great price. You have to be patient but there are some great deals there. Just do me a favor and look at the post counts on some for sale items. I love how guys will have 3 posts and want you to trust them with your money! Most are trustworthy but there are some scams out there and it seems even more here.
HTH,
