I'd go for the Halo as it's one of the most reliable loaders out there, and a PMR/SLG instead of an ion. Dye's build qualiy can't be disputed
Or check out the buy/sell adn get yourself a great marker for the same price! Cos otherwise you'll probably end up upgrading in future, and will have to sell off your Ion. And I advise not to think about upgrading your Ion so it's good, you'll probably end up spending a bomb!
If you're still set on an Ion, get the XE, it's easier to maintain and has a few other bits.
