As for power converters, I can get them made in the local electrical shops... We just need to specify the number of sockets we need...
I have heard both sides of a sunsun, for the most folks like them and are reliable.
If you have the money Eheim a better Canister. but the sun sun work well also.
gph on a AC110 is 500. so looking to go 10x well need 2.
I think you be fine with one AC110 and the canister. I would not feel right with my advice if i did not give the recommendations, in truth I run a AC110 and large canister on my 95g just fine.
