Robert,
I've spent hours over the last few days looking for a device for agitation and bonneting, and using the search button on this forum to find some unbiased opinions, and I noticed you singing the praises of the klanz several times, and saying you massively regretted throwing yours away. Well, its a bit lightweight for what I want, but there's one on eBay now if you're interested? I think it ends today?
And for the record, I find agitation makes a big difference, personally.
