The Kenmore is a good deal. Not a crazy tell-your-friends steal, but a very good price for all it includes. Offer less, but buy at the advertised price if they're firm.
The tower on the Danby is clearly cheaper, but may be (ask the seller) a larger diameter which makes it better for upgrading. Unless it comes with all the business the Kenmore includes, I'd say it's on par pricewise, but you have to buy that much more extra stuff separately. If it comes with EVERYTHING, including a tank (full or not), definitely get the cheaper one. Offer $90 but buy at $100 if they're firm.
I can't be arsed to keep up this list of what's in the fermenters, but hey, check out the cool brewery I own!
