Not sure I understand your question... your say "and not sprinkler system" ... so do I understand that you do not have a sprinkler system? With my sprinkler system, I have had good luck with toro popups and Hunter rotors.

I have had the best luck with a Craftsman Quiet Pulse Rotary Sprinkler. Its only available at Sears. There are two versions, one has a base that sits on the ground while the other has a spike that sticks into the lawn. The one with the base has a timer. With timer is $30 without is $20. I have gone through so many sprinklers its not even funny. This one is the only one that gives even coverage and covers a very large to very small area depending on your needs. You should definently try it. It really is fantastic and i know you wouldn't be disappointed with it.

I'll second the vote for a pulse type sprinkler in a spike. It is the best solution I have found for my smallish front yard. I move it around 4 zones putting it in each corner of a rectangular yard watering at 90 degrees each. My back yard has a wood fence around it which I dont like to water, so back there I just use a small simple square head sprinkler with holes. I can do the back yard in 4 moves as well. I use my timers and soaker hoses as well.
