as MIke123 says , it LX2 comes with 2 Sat tuners , the LX1 comes with 1 , i recently bought this box and it has only x1 USB at the rear (it does have one at the front - behind the facia , which could be unsightly) this is the only downside, However WOS were superb and im delighted with the box, no lag , and with the VIX image , works a treat.
