Firewire mixer/controller solution

Ok, so i'm searching for a firewire mixing solution for my setup.

mackie onyx (1604)
allen and heath zed (1604)

or then theres products like the yamaha 02R or the equivilent tascam.. but these are more software controllers with the added bonus of an audio interface.

whos got them? whos using them, WHICH ONE.

i'm gunna drop alot of money here and i need it to be the right product.. i've done the analogue mackie before and liked the build quality and its ease of use but the allen and heath is shaping up perfectly.. need to try it out!
