I waited long and hard before I made my decision. Its pretty obvious, if budget permits, to buy the ep500. I personally did not want to bother with a low end sub, as I had one already... I wanted to go all out and make the credit card bank some money on intrest.
. HOnestly though...buy what you can afford...but if you can hold out for the ep500 then it is your best option for today and the future. I dont even have it yet and that is my opinion. These guys on this board really love the 500...which is why I decided to just buy it and suffer the consequences.
Cheers.
