West Penn has great stuff, but you can't rely on it being dried. Most of their burls and chunks of wood are at varying degrees of moisture content and are not sold as "dried". I presume that much of their dimensioned stock is probably dried. A lot of Woodcraft's turning material comes from West Penn, and is not dried.
Never bought anything from Hut.
I've had good luck with turning squares I bought from Craft Supplies. Good quality and I thought the prices were fair. They were waxed when I received them but I removed the wax, jointed the pieces and let them sit for a couple months. No problems.
A good rule of thumb is to assume that any wood you buy that is fully coated in wax is not dry. No way for the water to escape. Waxed or anchorsealed end grain on lumber or turning squares is better, but is not indicative of moisture content (check with a meter).
Most places don't list their exotics as air dried, kiln dried, etc. You get what you get, so it is wise to get it through known sources. These materials are imported by companies in the US, but are pre-processed (waxed, cut) before they're imported and are sold as-is. They might have been harvested eight years ago or last week...No way to know without a moisture meter. Domestic lumber such as walnut, hickory, and others can easily be obtained dried.
