Thanks Nick. After speaking with Janspeed and they confirmed the price to be £389 at the moment and have ordered one at that price to be safe. Gaskets are only a couple of quid and not too much hassle to get.
Any reason why Janspeed are putting the price up? Have materials gone up that much? Seems unlikely but it's hard to see how something can jump 40% in rrp without justification. A lot of money for something that shouldn't really be more than £400-500 being that they have been out for a while now.

It wouldn't matter so much but it seems to be the best out there at the
mo.
Have you confronted them about the increase? Seems unfair that you have to pass their extra cost onto your customers.
