I use Namecheap too. I moved to them from GoDaddy and I can say that the interface is 100 times better. Add to that the fact that you are not bombarded with useless ads to buy stuff that you do not need (when all you need say is to register a domain)... namecheap gets thumbs up from me.
As for the discussion of namecheap.com vs name.com - namecheap wins by default. Name.com's interface is a lil' confusing. Just a little bit. Some words are used differently at name.com, so I guess that's where the confusion came from.
I use Namecheap. I'm actually selling a few domains on XenFans from my namecheap account for cheap, and I believe so is Miko. I won't link cos it's spammy, but the threads are in the XenFans marketplace.
