ABS is the cheapest, but hard to print.
The best is probably PLA-TEC, it prints like PLA, but is heat resistant till over 100celsius.
You can also try Colorfabb XT or nGen, but that has a bit lower heat resistance.
There are a few manufacturers of PLA-TEC ot there, like for example;

@neotko what was the brands again you used?
There are also some PLA's that need a treatment in the oven after printing to become heat resistant. I personally find that to much trouble....
