I have the Spyder3Pro. It's a great calibration tool, and there are many others out there. The price varies with make, model, and what it's designed for, but you could get older ones for relatively cheap (Spyder2express for $79 USD from Datacolor).
If you don't want to go the hardware calibration route, you could always find out the make of your lcd panel and look up color profiles for that specific one. Many ppl post them. There's a thread somewhere on here, but I'm a bit too lazy to search ATM.
Edit: Sorry, the thread I was mentioning is for MBP lcd panels, but I'd imagine somebody must have calibrated the same model as you. Just do a quick google of the model number and "color profiles".
