Digi 002 rack, ProTools 7.0 LE and Reason 3.0 for drums
and every sound/sample you will ever need.
Even with a low budget you should be able to buy at least
the Digi 002 rack, buy it with the Factory Bundle.
It includes ProTools 7.0 LE as well.
(1695$ listed on the website.)
It goes without saying that you won't get a better bang for buck
or better quality.
