The one I use by Philips has been discontinued, but I've been using it for 11 years without any issue so they've earned some brand loyalty from me if it ever needs replacing. They seem to have a few options at different price points.

My runner-up choice would be Hatch. I only have the kids version for our nursery, but it works great and they make one for adults that I'll link below.
