You could consider not nibble bidding.
Most experienced buyers would advise you to bid once and bid your maximum. (Remember to allow for shipping when you set your maximum bid.)
Many would also advise that you bid late to prevent nibble bidders from mischievously bidding you up.
The automated bidding will bid for you. You don't even have to be awake when the auction ends.
And if someone beats your maximum bid, then the silly fool paid too much, eh?
