4 and 8 tracks

Hey. I was just doing some searching on audio recording euipment. I want to be able to record drums and jam along while it replays. Do I need mics if I get a four track recorder or 8 track? Should I buy hardware for the computer to record instead? My sound card doesn’t work for recording. Any help or links about home recording would be much appreciated. Thanks.

I found this for 99.00. Is this agood deal ya think? http://images.misupply.com/products/originalzoom/Fostex/15790.jpg
