I use Readiris Pro 9 and it seems to work quite well for me.
I understand there is a new and improved Readiris Pro 11 out, completely rewritten from the ground up if memory serves me correctly. I didn't upgrade because Pro 9 is working well for me.
I think Readiris and Omni are about your only 2 choices. Readiris has a demo version on there website so you could download and try it out. Don't know if Omni does that.
