Jed I, where did you get your lance from? theres a couple on ebay for around 135 - looking at the video you posted you can change jets etc.
Thinking it could be a useful bit of kit, might even go chinese at that price.
After my 2 hand hand oriental one packed up, way back, I've not bothered replacing it - bought a gutter vac instead and have been pushing those jobs.
You're not thinking of selling your pressure wash stuff too are you?
