With a $1500 budget, you are going to have to take what comes along. It's not like people are selling great looking and working games if you are trying to buy at the low end of the range for the games you want. People always tell me they want to buy a game. I'm not usually much help because I buy at the bottom of the range and sell at the top. Once they get an idea of what they need to spend to get something they always want to buy alpha-numeric games at em prices.
And I go with High Speed for the best $1500 game. Taxi for the best $2k game.
