Several of you noticed the wheel in my Learning to Spin class description ... this wheel.
It's a Betty Roberts wheel. Pretty, right? Right! It's Aspen wood, an upright "economy" model, with an accelerating wheel built in. Betty always puts resin in, in a variety of colors (mine's purple, of course!), and embeds flowers, grains, and a bumblebee (her trademark) in the wheel. This wheel is double drive only, I'm not sure if that's always the case but I think so.
Others have blogged photos of lovely Betty Roberts wheels:

Yarn Girls, they do get Wooly (yes, the green accelerator wheel is the same as the one in Sachi's page! and better yet, I've seen that wheel in person - wowzer)
Another post by the Yarn Girls, more detailed views
There is a Yahoo group for her wheels with a lovely photograph section: SpinningWheels_by_BettyRoberts.
Oh yeah -- it's not for sale, LOL. Just so we're clear on that!
