Both calls you mentioned I have heard good things about. Other choices include Foiles, Zink, Sean Mann, Tim Grounds. All make polycarb versions of the acrlyics that can be had for $60 dollars or so. I own the Foile's Meatgrinder and am very happy with it.
As for low goose sounds, many(if not all) of the aforementioned call makers will tune your call to fit your needs. E-mail them before you buy and they can tell you if this is possible.
