Swapping out old PS box? Any suggestions on new one?

looking to swap my old and tired power steering box out for a new one. The 67 Dart 270 model slant six is going to be a daily driver so would like some newer feeling handling without breaking the bank. Any thoughts on a good model box that's pretty close to being a simple bolt on?
Thanks!
I talked to firmfeel last week and they had a 4 to 6 week turn around. Steer and gear had a week and a half and was cheaper after the core credit.

Heard good things about both companies.
Both have different levels of “feel” that can be set in the gear box.
