As per Ash's response, if there is demand we will more than happily look into it.
I recall Jon.G looked at doing one, but there just wasn't the numbers willing to do it, and to make a RR day worthwhile, we need a reasonable number of people.
Not sure where Ash was thinking of ringing, but my first choice would be EFI, we had our last one there and I'm sure they would sort us something out.
If you're interested, mention it in here or PM Ash or myself.
Cheers.
