Being left-handed, your options are limited, but even so, the RAR is a good choice lefty or righty. I have several RAR-Predators and all except the 22-250 have proven themselves capable of shooting groups MOA or better, but I'm still working on the 22-250.
CDNN currently has left-handed RARs in a few different calibers on sale.
