There is a newer vid at the Smart Parts site. There is a site w/ a guy firing one in the back of his store and was ripping a good 15+ bps it sounded like. (checking for the URL) I think it was posted on the vid thread or maybe it was a Google search.
I would be interested in the dusty desert performance of the Ion. It looks pretty solid to me as far as dirt resistance. I like Mags for machanical markers and Shockers for electro. The simple design seems like it would be good for desert play. Not sure how electronic spool valves will work in the dust.
Does the Ion have a spool valve like the others SP markers? Tuff call. I will have to find someone local that owns one so I can try it.
