Used Deeprock equipment comes up on eBay now and then. You can get a complete setup (powerhead, trash pump, accessories) to go down 100' for < $1000 if you are patient. You can get by using standard 3/4" black pipe for the main shaft. This is for the one that looks like a 2-cycle string trimmer on steroids. If you actually have to go thru any rock, forget it. They are not that durable.
