Aftermarket AC suggestion?

Hi everyone. I'm new here. Just bought a 66 Cuda S model. I'm down in Atlanta and plan to use it as a daily driver. We've had a mild summer but I still think she will need AC. Any suggestions on a unit to put in? I've known folks to buy the universal unit from Auto AC Solutions, but don't have any experience with other manufacturers. Any suggestions on which units work the best (or ones to stay away from)? Thanks!
