Who makes a good transmission????

I am looking for a transmission manufacturer who rebuilds 727 trans. I just had one rebuilt by a local shop. They did a really bad job. They are willing to refund my money so I am looking for a reliable and not bank roll breaking trans. I have heard some good and bad things about tci. What are your thoughts? Itt will be going into my Dart sport. It has about 350hp and I am looking for a stock type trans and conv. Nothing to beefy.
