I'd check out the Ruger Super Redhawk. It's a robust, well engineered & a popular wheel gun. I like the snub AK version(Dwayne Johnson uses a .454 snub if Faster www.IMFdb.org
The S&W 629, 29 & rare, light-weight 329 line are well made but many disdain the "lawyer locks".
The Nightguard S&W .44 is cool.
Taurus produced a few .44magnums but many gun owners & armed citizens do not care for Taurus firearms, save the Judge .410/.45LC revolvers.
The QC is iffy at best in 2013.
