I purchased it from Amazon. Go to Amzon and search for " professional foam lance adjustable with 32oz bottle ".
I bought mine for $59.99 w/ free shipping. Took about 4 days to arrive.
Can only be used w/ a power washer though! My is a 3100 psi, so really good in terms of foam making.
Also, check out "chemical guys" products. Mr. Pink will be the car wash soap that I'll be picking up for my Lance.
Good Luck !.
