I found the pricing surprisingly reasonable (not affiliated)

I just noticed they improved the pricing a lot since last time I checked.

Before you had free, 10k a month & $22 a month for 60k, now they added $5 a month for 30k and $22 a month for 100k.

Attribution for free is pointless, as with custom voices in theory it would be hard to detect and enforce anyways.
