I do love the colors. I have painted Indian Wells on my master bedroom and bathroom walls, and it glows. I was able to go with just one coat, also, but just like you, I had to use other Home Depot rollers.
However, much as I love the richness of Ralph Lauren's colors, and have no qualms with paying the extra $$$ for them, I am not all that patient. So, if I can find the same or similar tints in trusty old Behr brand paints, you bet I'll use them instead. They are a good one coat paint alternative if you can match the color you want.
