I went to Geavity.com and made myself a gear list and a wishlist.
My Gear List
So far, an entry-level DSLR, an 18-55mm f/3.5-5.6 lens, an entry-level speedlight, and a remote trigger. In my opinion an ok startup for a complete amateur like me.
This is if I ever get enough money to upgrade my gear, I'll probably go ahead and get a better speedlight that can double as a master commander for additional slave speedlights, maybe upgrade my camera to a D90 (one small step at a time) and procure some fast lenses for macro, event photography and portraiture.
