If you're not certain you want a lever, Steyr Scouts are now available with a threaded barrel and meet you "short and light" criteria. Personally, I'd hold off on any new Marlin product for a while to see how things work out under Ruger's ownership.

Used Savage 99's can still be found at reasonable prices in .300 Savage and .308 and are a step above any .30-30 since they can use Spitzer bullets and are a little easier to scope.
