We sponsor Golfgtiforum, we have the Meguiar's G220 and the Silverline Rotary in stock. If you are new to machine polishing I would recommend going for the G220 rather than the Silverline, as it's "safer" to use. It's a dual action polisher and so will not produce as much heat on the paint.
We also sell all the pads and polishers.
If you are wanting to order a G220 with a few pads and polish, drop me a PM or e-mail and i'll sort you out a very good price
