Lots of old posts available when you use the FIND function and put in Team One Showcase. Lots of good showcase advice on the site as well, try going through more of the Showcase Forum postings.
My primary piece of IMHO advice continues to be, "Don't overdue the showcase investment". I don't know Team One, doesn't mean they are not good, but I think a single PG Showcase appearance is plenty.
Good luck!
