For those trying to decide which Greek Bible they should purchase, Mounce has posted a helpful rundown of your options.
If you’re serious about learning and using Greek, I recommend you get two Bibles. (1) First, you need a Greek NT with a critical apparatus, either the UBS 4 or the NA 27 (both editions optionally include a Greek glossary). (2) Second, I heartily recommend the UBS Reader’s Greek NT. It will make actually reading the NT in Greek all that much more enjoyable.
Mounce also mentions a black-leather “stealth” NA that he uses. I was not able to find this. Anyone know where to get one? I always do feel a little self-conscious using my GNT in church…
Update: Phil Gons additionally recommends (see the comments) this post, which in turn links to this article describing the differences between the NA27 and the UBS4. The article will be of particular interest to those using Logos’s Bible Software.

Okay, I just read the Mounce article and I see he agrees with me.
You're welcome, Tommy. Thanks for the mention.
The stealth Bible Mounce mentions is a leather bound NA. I have not been able to find it.
The text-apparatus for the NA is difficult, but still easier than all those accent mark notations in BHS!
Thanks for the information. I added it to the main post.
