I've been going through the same dilemma over the past few days. Yesterday, I used DC 13.4 and there was nothing wrong with them. Everyone I know that uses them likes them a lot and they're very reliable. One advantage with DC is the lifetime warranty - and apparently, the customer service if anything does go wrong is outstanding.
Today, I demo'd some I was told about through local FBO . They're very inexpensive, but they fit my head really well and the mic was responsive. Very comfortable. I'm leaning toward these due to the price (3 year warranty) with the intention of upgrading as a reward (like USMCmech suggested) at some point - perhaps after my MEL.
The ones I demo'd today:

Good luck! Let us know what you decide on as I'll be curious to compare.
