Dirt bag, many people do use hardtails for this type of ridding, as a hard tail is an easy bike to ride, jump and pump. the other alternative would be to get a short travel bike, but i would not recommend this, as of the price. If you are just starting, i would recommend a Giant stp, a specialised p series or any of the norco dirt jump or street bikes, you are look at about a $1200 [AUS] for anything worth while ridding.
As a personal preference, i would recommend a Norco 250 2010, for the price, they are a great bike with a strong frame and good geometry.
Could I also recommend, that you perhaps work your way towards a hardtail first. Riders who use hardtail bike regularly become far superior in strength and bike skills compared to riders who purely ride downhill bike. It is better to learn how to pick lines, take impacts and build up confidence on a hardtail before switching to a downhill bike.
Also you will find that you can do a lot more on a hardtail, which won't only restrict you to Downhill trails. An example of this is, that i have a perfectly awesome downhill bike, but i still spend 95% or my time on a hardtail. even when ridding downhill.
Please consider this, so you don't hold yourself back as a rider.
