Event pictures.com looks OK, but it took me a while to work out how it worked, so it's probably not the easiest experience for potential customers.
I am going to take a closer look at Smugmug and take a pop at the free trial.
Exposure Manager is another possibility. I'll be using Express Digital Darkrrom software for the business which has Exposure Manager built in to make uploading easier. It's just a pain finding products that are aimed at European market as well as America's.
I'm pretty sure that Photo Store is the best product for my needs though. It's $300 with no other ongoing fees and looks pretty good to me (
Ktools.net | Sell Photos Online | Complete web based store for online proofing and sales ). It's easy to navigate and deals in Euro's, Sterling etc.
Thanks for the advice peeps, I am getting there slowly.
