I have the 1 HP model from Cabelas. I looked at the 1.5 HP but decided against it. The 1 HP has the same size feed chute as the 1.5, but cost a lot less. I have not been able to bog it down or stall it. My buddy even went and bought one after seeing mine in action a couple times.
Things I would look for if I were still in the market would be....Stainless steel, a feed chute large enough to accept larger chunks of meat (I hate having to cut the meat into little chunks just so it will fit in the grinder), ability to accept attachments if you ever decide to branch out, and a large enough motor to handle the job at hand. We make about 300# of sausage every year between me and a couple friends, and the 1 HP is plenty.
The attachments are great IMO. We added a meat mixer attachment to our arsenal last year and it makes all the difference in the world. You can also get jerky slicers, meat cubers, patty makers etc, that hook right up to it.
The .75 HP model would probably work well for what you described, but it has a smaller head which mean smaller chunks going in.
Cabelas is also known to have good customer service too.
