Thanks for all the replies and advice!
Current thinking is 8" - I'd rather get a couple of decent EPs and a Barlow straight off than wait, and I don't want to blow more than I have to on something that might not work out. Conversely if it
does work out I am happy to upgrade fairly quickly...
The tools etc I already have, the advice to search for manual collimation articles was well received (I don't mind tinkering) so all I need now is the scope and some fine clear nights!
@ Brendan: astrophotography is probably in my future (I have dabbled in photography most of my life) but atm I have neither laptop nor webcam. I do have a couple of DSLRs which I hope to bring to bear in the future, but I know the Dob is not 'quite' the right tool for that...
Thanks again
