Feeling Nostalgic - Police Academy 1 & 2 for $15 or Policy Academy Collection for $50

I'm feeling nostalgic. I haven't seen Police Academy since the early 2000's, but I grew up watching only 1 and 2. I really loved them as a kid/teen, but I've never seen the other 5 movies that I didn't even know there was THAT many sequels afterwards, but based on RT user scores reviews may not be the route. What do you guys think. 2 decent movies or plunge and see the rest for $50?
