I keep hearing pacer.org but it's not only a pay-for-results site, but it's also not user friendly for people outside of legal profession. I've seen a few people claiming they paid the fee and came up empty handed, either due to user-inexperience or lack of actual results, not sure which.
I want to believe this 10K is legit, but I've yet to see it demonstrated via YT or elsewhere by an experienced legal-anon. Would gladly pay the fee for someone to capture a demonstration.
