I have an Irritrol controler which is great, 18 zones, 4 different program modes and very easy. I have weathermatic rotors and pop ups. I don't find the weathermatics to be all that great as they always seem to need adjusting.

I don't know about the price, but I would stay away from Orbit. I don't like their heads at all, but I can't speak to their control systems or valves.

In terms of brand, I greatly favor Rain Bird and Hunter for valves and heads. The only thing I've had to replace on my Rain Bird valves are diaphragms, and that's probably because a) the system was abandoned for 2 years prior to my purchase of the house and b) there were broken pieces of PVC in the line because the former owner broke off the pipe when he removed the irrigation pump (he was a real winner).

I've helped other neighbors with their systems including their control boxes, and from that experience I can say with mild authority that Hunter and Rain Bird get it done.

I hear good things about Weathermatics, but I haven't used them myself.

In terms of your pricing, it's hard to say what's reasonable when we don't know about the number of zones and heads you'll have. Definitely get yourself multiple quotes and find out what control systems, valves and heads they'll be using. Get a projected layout as well.
