All round a very good aircraft but as with all aircraft years of flying teaches the manufactuer what was not so good about the aircraft.
These problems have largly been sorted in the Cessna 152 and so I would always recomend the C152 if you wanted to buy a small Cessna as the maintenance costs would probably out weigh the extra cost of the aircraft.
The only thing that was better on the C150 was the 40 flap setting, but I can see why Cessna dropped this as it was very much a trap for new players.
