Because they are just names slapped onto cloned tools, I'm just going to say Harbor Freight in general. You gotta do your research for each model you're interested in, but a good number of tools they sell are also EOL lines from big names rebadged and put into their own housings. I haven't been able to kill the $150 rotary hammer that I got 3 years ago, but I've had to replace high end bosch unit and dewalt units in less time. Both brands that I still love in their respective areas, but sometimes that name brand is flat out over-rated. And I'm finding more trades/pros just giving up on the random quality drops from the big $500-2000 tool buys, and just rolling the dice on the $200 copycat from HF with years of success.
And I love Skil's worm drives. I know they're bulky for some guys, but it's just dead reliable for so many applications. malcore might have some great insight on chainsaws.
