I started with TheSausageMaker & continue to use their blends, but I have to say that you need to add about 1/4-1/3 more seasoning than they recommend.
They are a bit bland, but have the right flavor profile for us, so I just use a bit more & am a happy camper.
There are so many to choose from but if you get on the mailing list these companies offer you can get some really good deal's. For instance TSM has offered free shipping with no limit on spending like so many others make you pay a minimum of 50 bucks to qualify for the free shipping. Everyone's taste buds are different but members on this site give pictures and reviews of most products that are available. Like Al stated , You may want to add some extra spice to a mix to satisfy your personal preference . Good luck shopping....
