Sorry to hear of your occupational status.
Are you a keen macro photographer?
If so, invest in a lens. If you're in the market to explore macro photography at a minimum investiture, then look at 52mm close up filters (+3 or +4 dioptres would be excellent on both your lenses).
As for lens recommendations, I'll need time to think of ones on a budget. At the moment I can't think of any.
+1 for this idea, I got a neat little kit off ebay for $18
this one here

they arent the highestquality, but do work fairly well. that way you can explore macro photography, after getting these I am waiting on my bonus check here in the next few weeks to pick up a true macro lens.
I will post some pictures up tomorrow that I took with them.
