Toughboxs have never failed on us, and weve used them for all 3 of my years so far. Grease them properly and they are great! If you want to use 4 gearboxes, then I say go for the Toughbox nanos, we used 3 of them for last years Kiwi drive system and they were also very good. They are like the toughboxes except only allow one cim, and have a one piece body.
