Out of curiosity, I checked Bill Mitchell to see what info is posted re Wedge blocks. Iron are simply "unavailable", while aluminum are said to be 120 - 160 days lead time. Aluminum is about $6K, and it's not "done"... maybe another $1K to be ready to assemble?

A quick check on the BBC blocks shows about $5K for an aluminum piece, and I a$$ume they require comparable additional prep work. However, their iron options are $2300 - $3000, whereas the unavailable BBM iron blocks are about $4300.

Well, that's TODAY'S info.
