Gary:
There have been many discussions on the List about Plastic
Frames, etc.
If I recall correctly, generally speaking the plastic hive parts
do not fare too well.... seem to warp after a bit.
We will see what others may have to say on the List.
You can do a search of the List archives to relive prior discussions.
