Hi guys, I am quite new to PAM so i need your advise. I've been reading reviews and tips on how to buy 111H for a while, but the more I read the more I get confused. 1. So, can anybody tell me where's the best place to buy PAM111H? I prefer unmodded PAM since my budget is about $350 max. 2. I read couple reviews about davidsen, some people says his new ultimate + new dial is the best unmodded so far, but some says the dial is wrong and also reports issue of his springbar. So... is davidsen PAM actually good or bad? And can anybody pls explain to newbie like me what's the difference between davidsen's and other dealer's PAM? 3. Any suggestion regarding my search for 111H would be appreciated. Thank you very much
