timing belt / pulley source needed.

I need to buy timing belts and pulleys for my Lathe conversion. I
would like a 2:1 ratio with the small pulley having a 16mm bore and
the large one being 12mm. The bore size is not so important if they
can be bored out. The biggest problem I have is price. Does anyone
know of a supplier with decent pricing? Berg is way out of line
with their price.

Thanks
Brian
