I'm seeing a lot more +$2500 people than I expected. Now I'm wondering how many of them are pro players that depend on good gear night after night. Thinking about modifying the poll with an extra option of +$2500 but I'm a pro.
Then you'll have to define "pro" as well. The bottom line is that any current production instrument is pretty decent these days and could be used in a touring or nightly gig situation. The more you use it, the more you'll have to take care of your instrument. Stuff can go wrong at any price point. There is no magic level where instruments become 100% reliable, nor is there a level where they are 100% unreliable. In general you could say that the more you spend up to a few grand the better the quality of parts and (hopefully) construction, and then beyond a few $K you're paying for more subtle and/or visual improvements.
