Maxi Bidder 1.83 is great. I bought MaxiBidder 1.6. and started winning a few auctions instead of just bidding and watching others win at the last minute. Started having problems when I updated to a G5 1.8 duo. Maxibidder support stayed with me all the way with suggestions, attempted fixes and updates until they got it going again with 1.83. The price is cheap for a great product and the excellent service you get with it is priceless.
