I'd do the 185 at minimum so you have AC capability and the 200dx if it's within reach budget wise and you want stick. Especially the new version since the pedal function is corrected. That 185 with a 25% discount is a very good deal. Actually both are, but the 185 is very budget friendly for the features compared to the other blue 185 on the market with very little adjustably! You should be happy with either, but get AC if you can afford it.
