EVANIX REX IN .45

I would love to get the Rex in .45 as it is cheaper then the Texan. It will only be shot a few times a year and I just can not see spending over $1000 on a Texan. But I have not herd much about it and evanix’s website well sucks. It would only be used for critter removal and a few other shots in a year. Anyone have one and if so how is it. Thanks.
