Killadoe,
I personally not a fan of break open rifles and like the falling breech hipower and BP rifles best. I just like the function and look. Since the scope is mounted on the barrel in both cases accuracy should never be an issue. I do think w/ the advent of the Omega it pretty much made all rifles that have a primer under the scope obsolete. Why would you want a rifle that is hard to get a primer in place, one that blows crud on your scope, or loose the longer barrel length for the same overall length?
If you buy used the bore has to be ABSOLUTELY PERFECT. Use a drop in bore light like the traditions one for 8 bucks. Well worth every penny. Make sure you bring a cleaning rod like a aluminum shotgun version w/ a 50 cal brush and clean it good and swab out. Any spots, forget it. Just toooo many great used rifles out there. Don't care how nice a BP rifle is unless it is a custom rifle from great builder you will never get your money back for them. They loose value fast...
Buy used get the best deal and spend you saved bucks on NICE scope, bullets and powder. The Nikon prostaff has the best bang for the buck w/ a true lifetime warranty. I'm a Leupold fan but you will pay 80.00 more min. I sell tons of Busnell and never have returns but for the working man Nikon is hard to beat.
What ever you pick, Shoot the heck out of it, understand it and you will literally have a blast!
JMHO.
