If you can hold out and basically stay a model behind you can get very good gear on the cheap.
That's how I've been buying my gear for years. I got a NEX 3 for $125. For Sony equipment, you don't even need to wait very long since they update their models so often. One year, they updated the Z laptop 3 times. Each time they did, the old model went on clearance at half price. I can wait 4 months to save 50%. That's why I'm so hesitant to buy the RX100 right now. I pretty sure that in less than a year, I should be able to pick it up for half the price it's selling for now.
