I put ordinary cable in black 13mm PVC tube used for garden irrigation systems. It has been buried for 6 years or so, and cost next to nothing, though you could always claim it is a gardening expense.
It is VERY difficult to pull the cable through the tube if there are bends in the run. Preferably lay the whole thing out straight on the lawn or down the road. Use a vacuum cleaner to suck a length of cotton or string through the tube, then use that to pull a fishing line or weed-eater cord through. Make sure that the ends of the tube are protected from the rain or the whole run will fill up with water and you have wasted your time.
