I use nothing but plain old yeast that I buy at Sam's Club. I get (2) 1 pound packages for about $3. I use it with my bread machine and also to make dough by hand. I've NEVER had any problems.
I looked at the little jars of "bread machine yeast", but at almost $5 for a very tiny jar, I refuse to buy it. I've been using the regular yeast for atleast 3 years now. I make some sort of bread about 3 times a week.
