Most places at the moment seem to be out of stock, but Amazon actually has some for sale at $150, and if you sign up for prime (then immediately stop it) you can get free 2day shipping or $4 overnight!
The Griot's is, per the specifications more powerful than the original PC and the Meguiar's machine. At the end of the day, it's all about the machine that works the best with the product you have on your paint finish. Just because it's more "powerful", may not mean it's "better"...
