Browning has a pretty good lineup of LH hunter models, beginning with the 223 in a 1-9 twist. I have not seen the SHOT Show specials but was told they are on the website.
The best news I got today was that the "Select you Tikka" website will go live within a few months. According to the guys in the Beretta booth, if the model you want is made in Finland, you can get it here, through your local Sako select dealer. I think this is a brilliant move that will allow left hand shooters a chance to get a rifle they want and not be held captive by what Beretta USA brings in.
