Most of their stuff seems to be large open crank exotica which, like hot fog, doesn't really attract me anyway (ie they can do what they like with the prices!).
It has to be admitted that I am something of a dilettante and 'my' sort of engine is something that; can be picked up without too much financial commitment, will prove distracting for a period of time either as a restoration project, stimulus for some historical research, or even just to tinker with, and which can then be tucked away at the back of the shed until perhaps an interesting swap comes along. I rather thought the Watermota might fall into that class (I'm sure I've seen the singles for under a couple of hundred quid) but clearly not.
