4AGE reliable seller?

[Ozone]

I bought an SMR engine from ebay.
To start with it turned up 1 month late.
When it was checked over we found cylinder no.1 throttle had grit in it and needed cleaning out.
When it was installed in the vehicle it ran for 20 seconds before making some very bad noises.
The engine was stipped down and it turned out a collet on one of the valves was incorrectly fitted - this resulted in cylinder no.4 being holed, two bent valves and the cylinder head was destroyed.
I couldn't contact the ebay seller by email or phone.
When I contacted SMR it was out of warrenty according to their records (although I had only had the engine for 4.5 months) so they wouldn't replace it.
I ended up sourcing another engine from Canada and having it shipped to the UK (which itself ended up being expensive because of a paperwork cockup by the sender).

So I would be very carefull about buying an SMR engine, particularly from ebay.
The seller on the link you posted was different but it used the same image so probably the same person so beware.
