Sorry to say - the car rego won out.
The other thing is space. I've had to downsize my work area - so much, in fact, that even my scope does not have a permanent position where I can just use it. This thing is just huge - and heavy.
(Yes, I realise the more I talk about it, the more I'm likely to talk myself into it - but even for $100, I'd be hard pressed to take the plunge ... and I'd still get into trouble.)
