blackcat, you most likely already know that our family has had issues with sped in our local public schools - so I can't help you with the "good experience". Two things to consider though, based on my limited experience:

1) In our area, the SPED experience didn't vary just with district, but with individual school, due to both philosophy of the administration at the school as well as the attitude of school staff

2) I found a wealth of information through our local parents' advocate group - they were able to tell me where my ds would fit best re services, where we'd have less success at getting services etc (which schools). If you have a parents' advocate group, I'd suggest at least giving them a call, explain that your dd is moving to middle school and ask what their knowledge of specific school situations is in your area.

Good luck!
