I've used Weaver bases and a variety of rings - the old Bushnells like SSK sold, now I use the Leupold Rifleman rings, three on the heavy recoilers (.45-70). SSK uses them now too.
I'd recommend you buy a used Leupold 2xEER - they are available on eBay for ca. $120-$150 if you can keep watch for a couple weeks (as I type this one is showing $117.50). They are FAR better than a cheap handgun scope (Simmons, etc.) on a .44 Mag, and they have a lifetime warranty.
The velocity difference between a 10" and 14" .44 Mag is not great; with 240-grain bullets Lyman shows around a 40-100 fps advantage, not enough to notice in the field.
