If you don't have it and have even a passing appreciation for the Marx Brothers, grab this immediately. The transfers are unbelievably good for material this old.
I suspect there are a lot of us who have done what you did insofar as buying Marx Bros. films on video. I also had some of them (but not all) on laserdisc.
That was exactly my thought. Universal floated a trial balloon for the boys with Buck Privates (along with their first monster meeting), but it must not have sold well since there were no follow-ups.
