As far as the boothies not using 'period' language or accents, that wouldn't trouble me, I know it's tradition, but the ubiquitous fake olde Englishe accents at TRF wear on me after a while.
Sure, but it's part of the experience of a Ren faire. It's corny as hell, but it at least means they're trying. When the vendors don't even bother to play the part, the whole atmosphere of the faire suffers.

Several of the vendors I recognized from TRF were there, but some of them didn't carry nearly the range of products at Scarbie that they sell at TRF. Son of Sandlar was one of them... my wife bought one of their higher-end pairs of boots last November, and I was thinking of getting a similar pair. But all they had were the cheaper models. I didn't question them as to why, but I'm guessing because the quality of costumes at this faire isn't nearly as good as the TRF, and they figure it's not worth the bother to lug around their pricier boots because the crowd here isn't the same.

I did buy my wife another complete wench dress and corset set from Boss Wench (who we bought her last dress from, 15 years ago at TRF). That set me back over $400. But seeing her in it was worth every penny.
