Micro chillers

[Dearth]

I currently have 3 fans cooling my tank during daylight hours and are struggling to do that and unfortunately due to limited areas I can place the room it is in is relatively hot and due to space requirements cannot run a full size chiller however I have heard about micro chillers and have 2 questions about them

1) does anybody run them and how well do they work?

2) Does any supply store in BC or ALTA sell them?
