I'm going with NextGen Pro Gallery, which includes the eCommerce functionality that I think I was using with Zenfolio. I can create proofing galleries, add a price list, provide digital downloads, password protected galleries, etc. It also has the payment integrations with Paypal, which is what I was using through Zenfolio. With Zenfolio, I didn't have orders go straight to the lab for processing, because I wanted to remove my watermark from prints, but leave it on digital downloads. With NextGen Pro, it looks like I can have the gallery add the watermark to downloads, so all I need to do to print is export from Lightroom to the lab and ship from there. I don't see it being any more work than what I had to put in with Zenfolio, but it costs me less and I don't have Zenfolio trying to market their own products to my customers.
