If the decks steel plating is under 2.75mm thick steer clear of it. Ideally you want 3mm plate. Anything less than that material wise the chassis will most likely be prone to cracking around engine mounting & handle mounts. That's the usual place steel decks begin to fatigue. For a steel base it seems somewhat lite even with a gxv160 on it. Personally you'd most probably be better off sticking with the tried & true. The ally honda may cost a little more however you'll know it will last a few years. You also need to take into consideration what other mowers you've used & still have & if it's a 21" ally honda then you have spare parts. Can't comment on nexlite decks as i don't have any. On the upside if the deck is quite thick then it should fine for a while. Other things to take into consideration is the gearbox & what it's innards are like. Are they beefy or weak. Too many unknowns. In the end it comes down to that old saying "pay once cry once"
