Yes, you can find samples of current and many retired SU stamp sets in the SCS gallery. At the top section of the SCS page (colored orange) there are links to other sections of the website. Click on gallery and it will open a page of Member's Galleries, Dirty Dozen Designs, SU Mini Catalog sets and then next on the list is Stamp Sets grouped alphabetically, Technique Spotlight Gallery, and a few other categories of galleries. However, during this time of website reconstruction, access to the sets gallery is limited to Fan Club Members ($24.95 per year membership). As I understand it, the gallery will reopen to all once again after the new system upgrade, etc. is complete. Let me tell you that it's truly worth the $24.95...the gallery is simply awesome with soooo many terrific samples of the work of soooo many really talented individuals. I'm not a SU demonstrator, just a stamping enthusiast and I've only been a SCS Fan Club Member for a few months but during that time I can honestly attest to the value of the entire site.
Hope you will find the same is true for you.
