The '328 ones are Pro Minis, although eBay does tend to make a mess of the labeling... both Pro Mini and Pro Micro designs are originally SparkFun Electronics in-house designs. Great company, but I wish they hadn't done those. I like the Arduino Nano (328) and original Micro (32u4) far better than the Pro versions. You may have noticed! ;)
As an aside, the Micro and Pro Micro are really just shrink-ray'd Leonardo boards. Whoo.
