Tommi's Billet M30 Rockers?

[Click]

I was going through this Finn's build and he had A Tommi billet timing gear for his m20, further research into the company found that they make billet m10/m30 rocker arms. Has anyone heard of this company or anyone using their rockers? They're considerably cheaper than VAC billet rockers.

At currant exchange rate 45€ is like 58usd per rocker so you be looking at like 700 bucks for 12, IE make heavy duty rocker for m30s and I think they are like 25 each so like 300 for 12, the billet ones look nice but I'm not sure why you would spend that much money on them and VAC wants 1800usd for a set and that's insane
