Another angle on this thread. I've got a Mk1 and I see no need to upgrade to a Mk2. The Mk1
really gets the job done for me and I actually prefer that plain 'home made' look of the front
panel.

So WRT to you picking up a second hand one; go for it. It'll certainly be a damn sight cheeper
than the Mk2. On the face of it you'll find it hard to justify the extra cost of buying a Mk2 based on
the additional features...
