i almost bought a toro super recycler but then tried out my friends. the sr4 has a killer deck but YOU have to push it up steep hills. that's a deal breaker right there for me.
ive got a 04 silver series 10234 that needs some parts. it has 5-10 yards a year for almost 10 years and the engine is still good I haven't put much into it either. I plan on buying another one in better condition. if I get lucky maybe a 10525. the 10234 there light, decent power, great self propel and last.
