I went and visited them since they're nearby me.

They do good very work but after my experience, I would get whatever part you need repairing magnafluxed by a very good shop first. Felt pen in any small hard to see cracks up front before giving them the work. They missed one on mine but we caught it later.
Here's a pic of a Hemi block they were planning on repairing.
