The experience you had with that company would make me want to cancel any plans I had with them, too.
Salt is easier to maintain. It doesn't evaporate out so it needs to be replaced less often.
But if you don't mind doing it yourself and do it well chlorine is just as good. My father has a salt system in his pool. I've swam in both. I only hate swimming in chlorine pools with too much chlorine or containments (urine ;)
If you try it out, make sure you ask him about his experience maintaining it.
You would never know there is any chlorine in my pool, yet it is perfectly clean. The problem is most people use pucks which raises the CYA which is required to allow the chlorine to survive in sunlight, but CYA also makes chlorine less effective and it doesn't burn off as chlorine does. So people who use pucks just increase the CYA to levels where you need ridiculous amounts of chlorine to be effective.
The fact my CYA is perfectly calibrated and no more is added the chlorine is very effective without overdosing.
