Hi Brett,

The best database to test systems is one that has its own forum on this site -- Price Predictor (now Bet Selector). It's very easy to use, has lots of kind people to help you, and isn't too expensive.

A word of warning however.... testing systems becomes very addictive. I find myself spending hours testing every combination of criteria available. Hopefully some of the systems I've developed will make as much in the future as they have on the past data.
