I have wide feet too. FWIW, I have had Shimano and Specialized shoes in the past. Shimano shoes seem slightly narrower and the Specialized have a roomier toe box. However, I now have three pairs of Louis Garneau (road and MTB) which are the best fit I've had so far.
Sidi do wide fittings too, but I don't think you will find those for $140.
