No PowerPC. You will need an Intel mac.
The way I see it, macs are expensive because they only sell them with the latest chips and technology. But on the Windows side you have companies that use much older technology and chips. So you can save money by buying used, there are several retailers that specialize in refurb and used macs. And at least they are built well, I bought a few over the years and have been happy with it. Just google it.
