I have one going in my boat this spring, i got a change to fiddle with the live model back in the fall of 2011, almost put it in the boat then but summer was almost over and didnt want to rewire my set up. Since then several revisions were made and this item is sweet.

Its aimed towards the WS420 but its still very different.
Big thing is no Mic on this little baby.
Good thing, the eq adjustments are automatic in the fact you dont set the indivual frequency as you adjust it up and down on trebel and bass it move all the bands to there proper curves.

I know for some they like all the levers and switches but i can say since i went to Exile brands and use only there cross overs for tunning, i have never touched a bass/trebel adjustment again and the music sounds so much richer and cleaner.

I will be installing one in March time frame and will give some reports after the stereo upgrade.

I know this doesnt help you now if you want the discount.
