i'd keep the etek personally. I guess it depends what it all comes with too though. I had a pmr with all the ups you could get except the metal backcap, and it was as nice looking and as nice functioning as you can get them. Nice marker, just nowhere near as nice as an etek in my opinion. You shall regret it eventually, at least I would.
they are alot more quiet then an etek but do not get anywhere near the efficiency.
dunno if this is allowed here, but heres the pmr I use to have.
