Equipment for my classroom

I have been using the Arduino Starter Kit for the last 3 years in my classroom and understand that they are going to discontinue the product. I have 11 kits and would like to continue to use them for a while. At the same time, I'd like to start looking at new kits. What recommendations do you have?

Some good kits here, education discount also.
