Has anyone looked at this?

I have an inexpensive 6" Ridgid jointer, and I hesitate to upgrade it with a Shelix head that cost as much as the jointer as I'd like to get a larger jointer if/when I get more room. The HSS spiral head looks like it could an interesting compromise, though.

The article I saw in one of the magazines (FWW?) some time ago didn't go into much detail.

For anyone who has one, was the install relatively easy? Do the blades hold up to figured wood, or (being thinner than regular HSS) are they even worse?

I'm not interested in adding junk. If this isn't worth it, that's a good answer too

Thanks.
