Probably cheaper and faster to just slap one together real quick. If it were me, I'd go to the hobby shop and grab some rounded lengths of styrene. Cut off a bit for a handle, then get a thicker width for the foam mic part and glue it to the top. Sand the edges to round the top and then paint. Fast and easy. Stick a Joe in your pocket and use it in the store to get the exact width to perfectly fit in his hand! If you already have paint, it shouldn't cost more than a couple bucks.
