My vote still goes to the Micro Cube for apartment practicing. If you get to the point where you need to play louder (i.e. jamming with others or actually performing), you'll want to buy an amp that was made especially for amplifying an acoustic-electric guitar anyways (i.e. the Roland Acoustic Chorus 60, Fishman Loudbox, Genz-Benz Shenandoah, etc.), or go direct-in to a PA system like the Phonic (which DOES seem like an excellent deal for the price, BTW).
I've had my eye on that Phonic PA system ever since Dewy first posted about it, and I've lost count of how many times I've almost pulled the trigger on buying one - but I'd have second thoughts if living in an apartment because it sure would take up a lot of real estate simply to be used as a practice amp!
