Where can a I buy a good quality ouija board? 
Not party city's crap board
gpt
make your own and buy a magnifying glass to act as the reading device

circle the ouija board and reading device with salt, and then chant the following:
veni ad me spiritum et fac me potentem
Chant for a good thirty seconds, or repeat it 30 times. Congratulations! You now have a spiritually charge ouija board. Use of it is the same as any ouija board, use a magnifying glass as the letter chooser or whatever it's called, and you may propose questions and ask for spirits to be housed in the board.

Just remember to say goodbye, or else the board might act as a binding agent for the spirit and it'll get ornery and hostile (like you would if you were invited into someone's house and not allowed to leave).
