Your asking a pretty broad question. Kinda like how much is a car. Lets see, just a few questions, Are you doing main line or drops or u/ dog fences. Where will the work take place, I/E what kind of soil conditions. What are the specs, How deep. Lots of bores or just a few. long term or a couple of months. I would suggest sticking w/ a used vermeer,"thats the yellow one". Im partial to the brand.
