Reply to eks xp 10

hi guys,
recently someone posted that EKS is selling the Xp10 controllers for around 100 Euros which should be a decent deal.
So I really was contemplating about selling my Total Control, which never really satisfied me for haptic and stability reasons, sell my Echo 2 Firewire soundcard and use the money to buy two of these and then rob a bank to get a decent 3 channel mixer.

So the questions are:
1) Does any of you have one and any opinion on it?
2) Furthermore I couldn't really find out how many audio outputs the device has, so I sort of guess that it just has two. So if you use two of the devices is there any driver that makes it possible to use both soundcards simultaneously in order to do 4 channel external mixing?

3) any suggestions for cheap and reasonable quality mixers with a minimum of 3 channels?

Thanks a lot
J.
