CubaseSE is only $99 and an excellent choice.
N-Track Studio (
www.ntrack.com ) is <$70 and also great.
If you want to do a lot of MIDI, go with Cubase it has better tools for MIDI but both CubaseSE and N-Track will do great with audio. I use both.
Go to
www.hitsquad.com .... they have a "Multitrack Sequencer" section with listings of multitrack programs. There are links to numerous demos, including demos of Cubase and Sonar.
Also immediately go to this link, spend $15 before you waste hundreds or thousands on setting up your studio and get this good basic book on recording:
