Murph,
Have a look on Ebay. There are some great deals out there (electronic & acoustic). I purchased the Roland TD-9KX (TD-9SX in the U.S.) earlier this year before the price increase. Shortly after I added an extra tom and 14" cymbal. Most drummers have G.A.S. (gear acquisition syndrome). I would strongly suggest that you visit a music store and demo the different models to see what your options are.
Good luck,
Shaun
