We used RATA for about 16 years and never had an issue with them. Great service, very attentive, generally easily usable product (HMDA). We recently left them though to move to another vendor that integrated with our new LOS better.
Once we got the data into RATA, it was great. Getting our data out of our LOS and ready to import into RATA was a ton of work. if RATA had integrated as well with our new LOS as our new vendor does, probably would not have changed vendors.
I don't repeat gossip, so listen closely...
