Hey Andy. I've done Fuze Block, Centech and Eastern Beaver PC-8, but went with a
HealTech Thunderbox this time. Super simple, flexible in how you set it up, no fuses, auto reset and will keep the circuit off if it continues to trip, comparable cost to some options. I used the TB-UO2 version and like it better than the other options for 8 circuits. There are vendors in the US, but I ordered it direct and it only took a few days. That was back in Mid March of this year. Very compact too. Love that you don't need any tools to put wires in with it's built in wire clamp design.
