So my local Exmark dealer is telling me they're thinking about having a sale on Exmark 21's in the next couple of weeks. Sounds like they're going to let the BBC models with the 6HP Kawi go for $995. Sounds like a great deal to me! Are there any differences between the Metro and Proline 21's that would make the Proline the better choice? Exmark dealer is close and seems fairly organized, I haven't dealt with them before, I guess I could use this as an opportunity to try them out.
