I have been using only plastic foundation (with the exception of my cut comb
and Ross Rounds(tm) production) and am very happy. There are problems with
the one piece frames as I have had the ears crack when prying them out. I
have also seen the problems with the plastic in wood frames with the bottom
of the frame coming lose from the weight.

In all I am leaning to the all plastic frames as my time is the most
expensive issue. If I were to put my cost of a plastic frame at $2.00US then
I have little problem with tossing a cracked frame out every so often.
Unless you have a well thought out production environment for building
frames and installing foundation I doubt you can get better than 5 minutes
per frame, or around 12 per hour (remember to include set up, sorting, and
clean up time in the project time). For me the cost of my labor plus the
materials makes the plastic frame/foundation products a sure win.

Of course if you enjoy working with your hands and assembling frames
provides you with the satisfaction of a job well done then the cost can
swing the other way very fast.
