Polaroid Land cameras?

Aside from the lack of manual control, my wife's Polaroid 450 seems like a decent camera. Cost us $30 for one in almost new condition.

The sharpness may not meet your needs but I have a hard time telling if we're hitting the camera or the films limits.

I like the idea of a manual one like the 180 or 195 but I'm not sure it would be worth the money to me.
