radio shack drum toy (or "Kool" -same model dfrent name

I'm seeking these radio shack drum toys. These also went by the name "Kool". They are black (body) and the four hexagonal pads are yellow. They have two speakers on the sides. When you hit the pads they make the four semi-cheesy drum sounds. They used to be around all of the time and now not so much. They are certainly nothing special and generally sell for less than $20 on ebay...I'm willing to pay $25 +actual shipping for each. Body condition doesn't matter so long as they are working.
