kids fencing equipment

Hi all: My grandchildren (10.5 & 6.5 yrs) are interested in my teaching
them fencing. I haven't fenced in 20yrs. but did teach beginners
classes for my fencing master so I have some experience at that level.
If they get into it there is a fencing school in my area. (Tucson AZ)
The local school was too intimidating and has other problems for them at
the moment though I agree that would be best.

1. Should I just get mask, plastron, glove and foils to start or should
I get the whole uniform?
2. Who offers the best value for the dollar these days in kid fencing gear?
3. Children's foils or full size? Can one even get children's foils
anymore?

Thanks
