Clicker for iMac

[Kevin Statham]

We use an imac in our tech booth to run powerpoints that then go to our switcher and then the projector.
Our stage is about 20-25 yards from the booth. Can anyone recommend a good clicker that can be used to go from a presenter on stage to our booth. Last time I tried it, a regular apple clicker didn't work. Is there an updated clicker that might do a better job? Is there another type of clicker that can handle the distance?

The Perfect Cue mentioned above will do it 100%, but I think they've been out of stock for a while (I'm assuming from the same logistics issues everyone else is also fighting with).
Second to that, I've found the Logitech remotes to be reliable. Your distance is probably outside the range of an R400, but we use an R800 for presentations in our small theatre at that distance, and it works great.
