If its just back-ups you want to play then go with the Duo2SE, it is VERY easy to install and is cheap as hell!
But where ever you buy it make sure you tell them you want the SE version as there are basically very little to no original Duo2 chips about, they are mostly clones now, so tell them you want a Duo2SE.
