[SIZE=2]For me, its definitely the revo although the gas variants have drinking problems. Maintenance wise, the revo is cheap and very easy to maintain base on personal experience. Price wise, the usual good units are pricey and neglected ones are reasonable.
the hilander has the better fuel consumption. its really frugal but problems are plenty especially with the clutch and the black smoke. Lots of low price 2nd hand units out there. we use to have one also.
adventures are plenty on the road, lots of parts available. very good fuel efficiency. [/SIZE]
