They had one but not in the colour I wanted.
I suggested a compressor because of all the other uses you will find for it. Plus I believe an air die grinder is a lot easier to control and is a lot safer to use. With the throttle switch/valve setup on an air die grinder it's easy to constantly control the speed of the carbide burr, flap wheel, sanding drum or whatever tool you have in it. This is important for controling the tool chatter against the work piece so it doesn't get away from you.
If you like when you drop over you can have a try of both types as I've got about 3 different air die grinders an electric die grinder and it's little brother the dremmel.
If you are looking for a cheap electric die grinder with a bit of grunt have a look at some of the routers that you can buy. I bought a cheap GMC or some brand like that router. The base un bolts and you were left with a beasty electric die grinder. It was designed to do this too. It's a bit bulky compared to an air powered die grinder but it works OK.
