I've put my weed wiper on eBay if anyone's looking for one:

I completely refurbed it a couple of years ago, stripping down and respraying it, inside & out. Haven't used it for a good while as down to spot spraying now, so cashing it in. Selling it without the sprayer (which I'm keeping as a handy size), so can be plumbed into your own.
