I bought a generic IR unit off the net for less than $15.00 and it works for my Aladin Prime and my Aladin Tec.
I Got a $3 dongle for my tec 2g and it works perfetly on my tec 2g as well.
It took me three tries to find a non-SP dongle that worked with mine. Cost me $10 at Tiger and it works like a charm so they are out there.
