This was my first time, Saturday only, and I loved it. I didn't really meet up with anyone from the boards (I'm not super social), but everyone I casually chatted with was extremely friendly. The Dealer Room was pretty nice, though I was kinda surprised by what was there, or more specifically, what wasn't there. I figured there would be tables full of Human Alliance figures (saw only 4, and wasn't paying $50 for Skids), Animated Arcees (saw none, just a lone Cybertron Ratchet at $25) and Recon Ravages (again only one). It wasn't what I had expected, but I was still happy with it, ($270 worth of happy, to be exact).
Took in the Hasbro panel, checked out the customs table and sat in a comfy hotel chair to rest my aching back from lugging around a huge ass IKEA bag full of goodies. Overall, a great time, and I'm already excited for nexy year!
