Agreed on the 4g proxies, however, yep, they can get expensive. If you really want to look legit and spend a little less, you can consider residential proxies as well, as they will make you look legit. I'd also suggest to look for a provider that allows city-scale targeting, as this broadens your possibilities and security. Furthermore, if you have that extra dime, you can go for dedicated residential proxies, which are basically the same thing, but you won't get the chance of getting an abused proxy, which might happen.
