One thing to note about CEE, and how it can be so cheap, is the percent error in creating the batch. In order to make creatine ethyl ester, you have to bond an ester group to the creatine molecule. This is not the simplest task, and therefore, it often does not attach.
Though it might contain some propaganda towards Muscletech, here's an aricle I was reading from another site:

One thing to keep in mind is that, although they are a little pricey, the bigger brands are more realiable for their purity.
Also, in the defense of NO stimulators, you can't call a free radical "nasty" for having a very short half-life. Short half-lives mean that the free-radical won't do as much damage as free-radicals with longer half-lives.
Another thing in the defense of "Arginine Products", you answered your second question in the reading. "How can NO result in pumps that last for hours?" Simple: it's not the direct cause. Look at the paragraph above:
The arginine gets turned into nitric oxide which then activates guanylyl cyclase. Guanylyl cyclease converts GTP into cGMP which then mediates smooth muscle relaxation causing blood vessels to become bigger and increased blood flow.
Nitric Oxide is the second step in a four step process.
