Landscape lighting

I thinking about putting in some landscape lighting. I've read a lot on-line, but there are tons of options & such. The brand most swear by is Volt. They make quality stuff, but they are also the most expensive. I don't mind the investment....I'm not getting cheap junk. Wondering how the install went, too. How many lights can be on one "run"? Any info or tips would be greatly appreciated.
We just moved in this year to a new place with zero landscaping. I'm still in the drawing things out on paper stage, but Iwill eventually install landscape lighting once I get it all figured out. I am leaning towards Volt due to the numerous recommendations and lighting options.
