I have been using Telerik controls for about 6 months. I use the grid and window controls on MVC 2. Like most commercial products, there are problems that we were lucky to work out. After you go through the initial learning curve, the controls are time keepers. You cannot beat the price for the amount of functionality that you get.
My biggest problem is that they seem a bit sluggish in their forums. Maybe I'm just asking lame questions. I lobbied management to pay $ for the supported version. Given the amount of time we spend solving some of the more complex problems, I think it was worth it.
