I just used a channeler this morning and it was literally less than 5 minutes from taking my prints to receiving the email saying that my report was ready. And that only cost $50, compared to $18 plus $5 for fingerprints at the local police station for the nearly 3-month long standard FBI process (and I got to pay both because my left hand's fingerprints are apparently awful
).
To be clear, the channeler's site said to expect it to take 3-5 business days, but others on this site have used them and had it be just as quick.
