Couldn't agree with this more. I also have a low-priced SAAS product [0] and spent a ton of time early on talking to new users who signed up. I wouldn't even call it "sales". I just wanted to hear from early users' own mouths why they had signed up, what they hoped to get out of the product, and how it was working for them so far. These conversations (which I still do today) provided invaluable insights into how to improve my product.
