I can't recall where its located, but there's another thread on this site comparing the 2M Black to the 20XL and the concensus was that the 2M would be a step down from the 20XL.
I'd also recommend Soundsmith. I currently have a 20XL and the Aida or Voice are on my hit list. A buddy of mine switched from the 20XM to the Voice and he absolutely loves it.
