When I was there we still used the MKII and the MKIV, not sure why they started to use AR15 for their drills, you can do rotation on the AR15 but the thick rifle grip makes it harder to grip.
Digicabi having sales analogue ones are are good prices if you not picky a 40L analogue is going for $99 can get at photography shops like MS Color, Alan Photo and John 3:16
IT-image is selling Qcool at $69 no HDD, also most shops in sim lim selling similar, same chipset just the case different about that price too. Fulwell the other time I saw but not Qcool.
All current and potential Pinky:St owners please beware of imitations on the market. From what I know Comic Connection sells imitations, check the paint work and the packaging before making a purchase, prices should be about $10.90 onwards, unless got special offer.
