Digital photography

Get a second hand D100. Then spend the rest of your money on second hand lenses. Spend as much as you can afford on the lenses, not the body. The guys at http://www.apertureuk.com/ will sort you out.

If you'd said D90 then maybe, but D100? Come on... Yes investing in good lenses is the thing to do, but not at the expense of a better sensor, better autofocus, better handling - basically 6 years of digital camera improvements between those two models, and 10 since the D100 was released. There's a sensible middle ground for the DSLR purchaser in 2012, and the D100 is nowhere near it.
