To be honest Paul, i normally would, the only reason i didn't in this case was because every time i look on ebay they are normally some after market crap, the one Maurice found seems to be a genuine Eiki which is ideally what i would like. (now purchased).
At present my machine is with a projector service engineer ready for collection, although all the work it went for is done he didn't have this belt and the SL2 belts are different compare to the more common NT and RTs, he didn't have one in stock and at present it isn't detrimental. I want to get one for the future as it will eventually go and i know these machines are not that common so parts are no longer easy to find, it is a darn good projector though. .
I must admit to forgeting the other ebay sites, i always tend to go into the UK site. I know i miss out on a lot when i forget those sites.
