Was looking for a foamer to remove grit from the paintwork before starting to 2 bucket wash....
Ended up purchasing this one from ebay:
Gilmore Foamaster II.

Ive seen a few others that run from a karcher or similar pressure unit. This one uses mains water.
Now to search for a decent foam concentrate... or just use my megs NXT wash....
Though a few people might be interested in foam lances...
++++ EDIT+++
For those that are looking at these, there is a fixed dilution ratio (4:1) version The 95QGF4 and the 75QGFMR is the multi ratio (1, 2, 4, 6, or 12 oz. per gallon) jobbie...
Ill post up results once it lands.
Vid of it in use:
