Unavailability of the adjustable rings is going to wreck my plan. Namely, to get one of these quality outfits cheaply.
There's a Stith-Kollmorgen 4x scope on Ebay that looks nice, and it's only $20!
But if you can't buy the adjustable rings, or if the adjustable rings are expensive, it won't work out.
Dixie Gun Works has some rings, but Hairtrigger is correct - usually the rings come with a scope. And most of the Dixie rings are not click-adjustable.
