If you are going to scope, the base and hammer extension from this page: 18.00

and for a scope, to keep total price down, perhaps a Banner 1.5x4.5 or a little Millett 1.5x4. I really like the little Millett for the money. ~60 to 80

An alternative to a scope if you've still got good eyesight might be a nice peep with matching front. Likely wouldn't be much cheaper though.

I get a total of about 279 from the above. You are still going to need scope rings - good weaver style -and will have to pay some shipping so add another 50. Throw the remainder into a good range rod.

Hope you weren't figurin' on powder/ammo/primers in that 350.
