Remote options for D300?

I picked up a "Pixel " OPPILAS http://www.pixelhk.com/Proshow.aspx?id=78  wireless remote last year ,at a bargain £18 ,I dont know what that is in USD ,but cheap . it works superbly and has all the usual options , single/continuous/delayed /bulb etc, and has a brilliant range (100m) and actually works well at that range unlike some other makes that work intermittently and barely half the claimed range.
