Cheers, hopefully some others can post, id rather it went for a bit less and stayed in the UK but ill wait and see what others come back with.I'd suggest ebay for the six pack and offer international shipping, bet it'd go to america for more that £70, especially if you let people know about it on mcarterbrown / pbnation.
The line SI is a beauty the lever changer and the extra barrel only add to it. Not sure on a pirce I'm afraid, I know if it was mine it'd take at least £80 before I'd conider selling but that doesn't mean that's what its worth!
It's mainly that the vents in the bottom are more than big enough for a paintball to go straight through. Plus the lack of ear/temple protection as you said. While the Elite frames are awful (not thermal and very small!) they themselves are actually fine to use.They use JT Elite lenses if I remember correctly,not too sure if sites would let you wear them due to the lack of ear/temple protection.....probably still offer more protection than a set of i4's
