That looks to be a better size than the prybaby's. It's hard to determine the size of these from pictures with no reference or context. I guess everyone in the Atwood thread knows all of the sizes by heart. I think I want one about the size of a Bic lighter. The roid models appear to be of similar size, at least big enough to hold onto. It will likely never get used, as described in this thread, but I may try to pick one up.
