I understand the ODE devices are easier to link together with a router, than a USB PRO and requiring extra usb ports. Beyond that not too sure as I've only used my USB PRO I had from doing lighting previously.
As I was told in another thread, don't hookup ws2801 to a RGB dimmer/decoder. ws2801 has +, CI, DI, - for connections (most ws2801 are 5v, and don't have RGB wires like the decoder you linked)
You'll want a decoder with +, CI, DI, - to match up with the soldering points of the ws2801.

With a ODE you get 1 DMX universe of "addresses" (512). So say you have 5M of ws2801, and each meter has 32 led 'pixels' - that's a total of 160 pixels.. Being RGB strips, each led 'pixel' takes up 3 channels in the DMX universe, so we multiply that number by 3 bringing the total DMX channels used by 5m up to 480 of the 512 available. The more pixels you need, the more DMX addresses you require, and more ODE or artnet devices to give them the space required.
Personally I just took apart an old computer power supply I had, grouped all the same coloured wires together and made a "lab" style power supply using the red +5v wires and black ground wires. However that one you linked will not work with ws2801 strips as it's a 12v power supply, and ws2801 use 5v power. I plan on purchasing some similar metal cased power supplies, but they will likely be closer to this -
