I've heard a bit about the following services, are they any good?

The Players Klub TNT

Or am I best of just using Kodi Solutions? Or is there another cheap and semi reliable service?

I've tried a couple of services, and they just buffer and buffer, or the channels just plain don't work.

I know it's not my internet speed, as I had Gearstv which had worked well, but is a bit on the expensive side for 3 connections.

I need US channels, and would like sports to be there too.

I understand that IPTV is not foolproof, and there tends to be some hiccups and such, but I am looking for one that is reliable as far as IPTV standards.

Please help, and thank you for your input.
