As for brands, there are many brands, but apparantly only one maker
in china. Yanmar, Kama, etc

_Engine.html
Above is a link to one site. If you look on ebay, or machinary
supplies, ie generaots and water pumps, you will see the very same
diesel as it appears to be the only one, but branded by all// the
Yanmar will cost you around 1000 to 1500 dollars ! - for the
name !.. complete new pumps with frame can be bought for around 450
dollars on ebay, new.. I beleive they are ALL the exact same engine
from the same source.
