Best Site For A Stable Proxy

Need a single proxy to use on my Paypal and Ebay.
Must be UK.
Where would a good place to get this be?

you need a deacated ipv4 anywere on google or on this forum

Would recommend checking out the Residential IP proxies. Most of those on the list should have UK IP addresses.
I have tried a few of those services covered, it was a great investment - https://medium.com/@raimondofanucci/top-5-residential-proxy-providers-2018-dc69d9503155
