My sister got me one in November. They're pretty cool, and I was using mine every morning for smoothies with frozen fruit. There is a problem though - after around 5 months of use, it now has a short. I put the stuff in, put it on the base, and it goes for about 1 second and stops. That happens over and over till I get lucky enough for it to work. Another problem is that the blades got dull really fast.
That said, yes, it's a very convenient purchase, but you can get them for quite a bit cheaper. I've seen them at Kohl's on sale, and that store always sends out coupons.
As for recipes, like the people before me said, use blender recipes.
