Wow, thanks for that post, Nik12.
That explains a lot, and saves me days/weeks or researching! lolz
Unfortunately, I'm not at home and I can't read that review you linked on this computer (Restricted), so I'll get to that tomorrow.
One question though - in your opinion, what brand would you recommend? There are a few that offer the MP5 SD(5, if I can find one) models in full metal bodies, so I'm curious to know what brand you would lean towards.
Note - I've got a buddy in Vancouver that is right into this sport, adn he told me to talk to him before purchasing because he has a good line through a guy out there, so I'm just still in "research mode".
