I'd imagine that Ken is offering you his best price. Besides, knowing Ken, I'd suspect his mixer is a better quality unit.
Interestingly, I have a mixer that I bought some years ago at Sears that uses a top link that is threaded rod and dumps the drum with an over center motion rather than by hydraulic action. The PTO drives 2 rubber tires via a roller chain and jackshaft and the drum rests on the tires and that rotates the drum. It's 3 bagger and every time I look at a bag of Kwickrete and see the words "Just add water and mix", I cringe. Just add water is okay, but the mixing, well, that's another story, that is, unless you have a cement mixer. /forums/images/graemlins/grin.gif
Drum mixers have many other uses other than concrete. We use ours all the time to mix feed or add supplements, you can mix fertilizer too.
