Well it seems like your probably going to buy a hardware drum machine no matter what (once you have your mind set on gear its hard to resists), so if thats gonna be the case, i would definately try not to get too crazy.

I would invest most of my money on a good CPU as dodgey had mentioned above, a nice pair of monitors, a midi interface, and run your software on the computer. In terms of hardware, i suggest you to buy a maximum of one drum machine and one hardware synth. Learn the machines inside and out, and once you feel you have done all you can with it, sell it off and replace it with another machine, but dont start out in music production buying all this fancy gear because it will hold you back. Instead of collecting gear, try to replace exisiting gear with something else, because it can become quite overwhelming when you have too much stuff to fiddle around. Its counter-productive.

By the way i would recommend the NL2X. Its the only synth i use out of my 4.
