For the price of a new combo, you could probably get second hand Ashdown separates, that have already been 'tested' for reliability issues, and give you more versatility. I found Ashdown to still provide good support for items you didn't purchase directly (in that they told me how to fix them).
I've had the EB180-15 and have the EB150-12, the 12 is ported, but I preferred the 180-15, it was a later model though, significant improvements visible inside, guess the new one with compressor is better still.
