The Marketplace page seems to load weird.  While the first page makes it look like there's only 3 pages, there's actually 8 and some of the items are varied.  It really depends on what you want to get out of Genesis.  I've learned there's various ways to "cheat" to expand things (V4/M4 poses tend to work on Genesis, skin tones can be transferred over, Autofit has varying degrees of usefulness) but it takes a small bit of risk.  Or...exploration.  If you see something that looks interesting, ask around, download the product's readme, and read the reviews other people have left.
