help finding metronome...

I had the best free metronome before i formatted my hard drive and i forgot to save it. I have searched for it and cant find it anywhere. I dont know the exact name of it. all i know is that it is green, it says "start" on the left side and "stop" on the right side, i believe. If you want to change beats, you turn a big dial. It goes up pretty hight too, way past 200 and even 300. If anyone knows the name of this or where to get it, plz let me know. Thanks

Chris
