Lego Robots

I would like to buy some Robots kits like provided by lego mindstrom.
I visited their site and found that those were costly.
Can any one provide me the links for similar products for robotics but little cheap.

I thought mindstorms were on the cheap end. No need for tools. I dont remember seeing another kit like Mindstorms that still had the toy classification. Most of other ones Ive seen are more for proto-typing or education sets and cost way way more.

Like this one:

Tried Radio Shack yet?

This is the search page I got for their Vex line of robot stuff:

It has been a while since I priced Mindstorm stuff. Still, it seems this is less expensive overall.

'Luck!
