Let me check with my Distributor and I will see how much I can get you a set of the 720PRS for. I will let you know tomorrow and I will be able to offer you a small warranty also, just because you are a fellow forum member!
Once again i will say check out the Blaupunkt VC660 or VC650 this system has a lot of great feature built into them that you will fine in systems costing 3-4 times as much and they sound very good, DLS/Dynaudio like. For what the can be had for you will not find a better set even at twice as much.
Heres some nice reading on this set from over at DIYMA
