Welcome, J! Congratulations on the gift - that's outstanding.
I don't know the equipment kits for Coopers or Brewer's Best - if you post links to what you are looking at exactly, people can give you their thoughts.
Also, if you look at the major online vendors here, they all have really good equipment kits. I sometimes order from Seven Bridges and they have an equipment kit that includes your first ingredient kit, too - and their ingredient kits are outstanding.

Here's another one from a good online vendor, too

If you look through the vendors list here at HBT, you'll find reputable dealers who can sell you what you need.
Happy brewing!
