Your photo sales experience with Zenfolio

[kxl]

I currently have my own website/blog, but really don't maintain it regularly other than upload more photos, some of which I believe are interesting enough to sell. I don't really want to deal with the e-commerce and fulfillment, so I am looking at services that do just that. Zenfolio and Smugmug seem to stand out, and at least for now, I am leaning towards Zenfolio. I'm on the 14-day trial right now, and playing with the different features.

For those of you with the Zenfolio Premium Business Plan, what has you experience been? Are you generating sales? Getting traffic? What genre seems to sell? Landscape? Abstract? Street? Others?

Any thoughts? Advice?

Thanks.
