Best emulator to date is a cheap $300 e-machine computer. None of the PC emulators on mac work very well with high-end graphics type of games. I have set up 6 of these computers for my mac friends and even though they don't like PCs, they like crashing planes even less. All of them have been happy with the decision. It doesn't have to be an e-machine. Just make sure you don't get a Celeron processor and you will be fine. Overstock.com and Ebay are two places to find inexpensive PCs very cheaply.
