scope rings for 30 mm dot

I went to Fleet Farm and Walmart to get some Quad lock rings for my 30mm dot and they were out. I like them, easy to take off scope with the 1 screw and are cheap, great rings. Looked on Weavers website and they don't make them for 30 mm. They make other rings with the 1 screw attachment but they're over $40.
  I do take off scope to thoroughly clean slides once in awhile and get sloppy with the solvent.
 Any suggestions ?

My favorites are the Weaver Tactical 99515 (2.9 ounces) and the Warne 213M (4.6 ounces) depending on how much weight I can add.

One of the better ring sets.  Buy once cry once.

These are good, cheap too, but you do lose zero if you remove your scope.

I ordered the rings DA/SA referred to great price and just like Weaver brand except for the smaller head on the bottom screw. I ordered the medium and short height ones. 
 Thank you much, Stan

They are cheap, unfortunately they strip quite easily. They are the same I believe as the ones supplied with the 9000sc which I stripped. I no longer use rings that have the crossbolt going into just aluminum, the Weaver rings I listed above have a large steel stud that the cross bolt threads into.
