Yeah - I thought it was a good price too. These guys did the timing chains/tensioners etc. on my VR recently, so I know they will do a good job. It's fixed price too, so no nasty surprises on the bill when I pick her up.
On the subject of head gaskets, I had a mate who worked for Lotus. They had a seriously visually impaired (ie only 20% vision in one eye, completely blind in the other) lad working for them doing an apprentiship. They had so many Elises in with blown head gaskets (God bless the K-series!), that this lad could do a complete change in under 2 hours without supervision! Apparently his spacial awareness was fantastic.
