Thanks for the reply David. 
I don’t have a set of 8mm collets and it is the one thing that worries me about investing in a Sincere lathe. I would hate to invest and then find out the collets are not up to scratch. I think unless we can speak to someone who has a set to see if they are ok, it could be worth finding a good set of 8mm collets first before buying the lathe. I would have no difficulty making up a drawbar to suit whichever collets I ended up with. So many of the used collets knocking about now have been mistreated and its always a bit of a gamble buying them used unless the seller is willing to accept returns.
