I've had some shimano m520's about a year, roughly 1000 miles on them. Only commuting use, no rain or offroading. While I weigh a substantial amount, I would expect these to last a lil while longer, but they're both audibly clicking/grinding now. I know they are rebuildable, but the cost does not seem justifiable seeing as they go for $25 or so new. Does anyone know of a more robust spd style pedal that's reasonably priced ~$50 or so? Got some candy 1's but they eat cleats. TIA.

Edit: Let me know if I am being unreasonable.
