Thanks Nettie. I took myself into Bintel's in Camberwell today and they said pretty much what you said - "Keep it simple, stupid!" Unfortunately they are out of stock of 8" Dobs at the moment and also pretty sure the next shipment is over committed already. I had a big think about a 10", but I really think it might be a bit cumbersome in my environment. Anyway I think I might have sourced something second-hand from the IIS forum....
