I see that Collectors West is a 3 day show every other month and Rose City is a 2 day show. Any big difference between them? Are they about the same size? Is it just a cost issue of renting the Expo for 3 days vs 2 days? Need a couple of items, but not immediately. Would like to look at more than one without having to travel all over town. I'm looking for some accessories and not guns. Thought I'd try the show. Really want to go this month and just wondering if there's any big difference between them.
