I'm in the same boat. I want to take decent pictures, but don't want to learn all of that f-stop, bokeh, aperture, etc. stuff. The light tent and a good point and shoot seems to be doing a fair job right now, but I wouldn't brag about my pictures. I'd invest in a high end camera, but with my lack of knowledge of photography, I believe I'd be wasting my money.
Oh, and cool pictures! It is getting a little cold here for back yard herping.
