I use Cubase SX on my pc, its the next best thing to ProTools (which works best on Mac). It's not cheap but if you are thinking about reasonably serious home recording then I would advise this as an investment. Most professional recording studios have a copy of this on one computer so you can export directly and have an engineer master your home recordings. I invested in a Tascam US428 as an outboard soundcard, it's a cool addition to Cubase as you can use the faders and jogwheels etc which directly affect the software. This is very handy as using a mouse to turn little knobs and dials on the screen is soul destroying.
