The right tools for the job
Recently I got myself a new dremel , it's a warrior brand drill and it's great, although I personally find it a bit too big (you'll see the size of it compared to my old drill) but yah know this got me wondering, what y'all consider the right tools for the job? There are many different drills and dremels out there so I'm curious to see which are the most reliable.

I have a Dremel, I believe it's the original Dremel brand. It isn't cordless, but we have plenty of outlets in the garage. It looks about in between your two, size-wise. Definitely a handy tool to have around!
I use Dremels. My current one is still doing fine and I've had it for twenty years or so. I don't see any reason to consider any off-brand rotary tools, I'll stick with the industry standard bearer.
The Dremel was my best friend and is the workhorse, imo. Lots of various sandpaper was probably the second most used. And honestly, lots of various size/length toothpicks, popsicle sticks, and little pokey things are invaluable.
I have a real Dremel, plus about three of the HF rotary tools for various applications. The Dremel is the workhorse, while the others are used mainly for specific one-shot purposes without having to change bits in and out.

can't go wrong with a good cordless rotary tool! If you go to Harbor Freight, they have good reasonably priced bits and other accessories for 1/8" shanked tools.
