Spin Caster Help (Closed Faced spinners)

[HuckFinn]

I think I know the answer to this question, but with all the knowledge on this site, other ideas and opinions can not hurt.
Every year my wife and I work with some special kids and adults at a fishing day. I want to pick up 4 or 5 poles for them to use.
Spin casters are the way to go ( closed face spinning reels) for these guys and gals.
My question is how good are the plastic reels.
At the store I have metal combos for around 30 dollars.
Plastic combos in a package with hooks and stuff for about 20 dollars
Metal reels for about 15 dollars
Mixture of rods from 9 to 100 dollars
I would like to get the metal combos but do not have enough of them. Only 3 in the store.
I am thinking of picking these up now and hope to get more in before “Fishing Day” in March.
Plenty of plastic boxed sets, in the store.. Not sure if these will hold up for the day. If the outfits only last one trip that will be fine. However don’t want them to fall apart until after the fishing is done.
Not sure if I want to buy the rods and reels separate.
Am thinking that if I do get the metal combos or put my own outfits together, the folks using them can take them home to use next year.
What do you guys think about the plastic boxed sets. Will they last the day?
Thanks C ya tonight after work
