If I had to define myself, I'd say addict/enthusiast. I've been paid to take some shots here and there. But I didn't enjoy shooting what others wanted. Now if I can go sell stuff that I shot for my own artistic tastes and make a good living at it, that would be wonderful.
I personally define a professional as someone who uses photography as his/her primary income source. If if make a substantial but not most of your income from photography, I'd say you're a semi professional. If you make a few bucks here and there, I'd say amateur/hobbiest/enthusiast/addict or what not.
Cost of equipment or what gear you shoot with is almost irrerevent as I've seen amazing shots with a p&s and generic snapshots with the most expensive professional grade gear.
