3M stripper wheels Where is the best deal

[FORDification]

The versions from the local farm-supply store are the same price as those from Eastwood, but a few months ago I stopped in at the local Harbor Freight outlet and was surprised to find a similar generic product for about half the cost which worked just as well and lasted just as long. However, I haven't seen them listed in their catalogs or on their website. The next time I'm in the neighborhood I'll be stocking up on some more.
