Say Intentions - AI ATC

I agree that price is a big difference. Given the money I just put into my new sim set-up, the cost is in the noise for me. There is a slight delay in SI responses, but it's scarcely notideable. I haven't used BeyondATC, so I can't really make an overall comparison. I'm not advocating SI as an alternative to BeyondATC, I'm just relating my experience using it.
