Is there any service that competes with ExpertFlyer that also offers seat maps, similar to what ExpertFlyer offers under "Seat Alerts"?

I fly maybe five times a year, so paying them $60 for seat maps is unattractive to me. I would be willing to part with about $10 for a limited number of seat searches per day.

The other thing is I hate the way ExpertFlyer implemented their feature. I do not want a seat alert. I want a way to investigating seat availability whenever I feel like it. You cannot create a SeatAlert without creating an email notification when specific criteria (e.g., a window seat in business class) are met.
