I tell ya guys, I'd love to have a set of those for my FED project but I'm afraid of how much they will sell for in the end and how much it would cost to get them running correctly. Also don't you need a pump and a few other parts to make them run? I don't know, you spend a bunch of money to get something like that and it ends up sitting on a shelf.
I think I'll just go with carburettors. Sure looks cool though.
God Bless.
