I figured I'd just go to our local hardware store and get what I needed, but I've done a little reading and it seems there's bad pipe out there as in it will rot through quickly. Rather than what I should look out for (which is also ok), what should I be looking for.

I'm figuring single wall black pipe from stove to ceiling, double wall (class A?) from ceiling through roof, triple wall chimney?
 
If the stove connector is under 8 ft and single wall clearances can be honored then go with a good heavy gauge stove pipe, not the thin snap seam pipe. It will often be seam welded and will last a long time. Double-wall class A is fine. There are several good brands on the market. Selkirk & DuraVent are popular brands.
 
Stove pipe goes from the stove flue collar to the transition to Class A chimney. Stove pipe comes in single-wall or double-wall. The difference in application has mostly to do with clearance from combustible materials...single-wall requires 18", while double-wall can be placed as close as 6". Single-wall stove pipe comes in different forms and different gauges (thicknesses). The cheapest (24 gauge) stuff comes in flat sheets that you have to roll into tubes and get the joints to snap together. I hate that stuff. The better (easier to work with) stuff comes already in tubes, but with crimped seams. Meh. The best stuff is heavier 22 gauge and has welded seams.

That stove pipe gets you from the stove flue collar to the transition through the structure (wall pass-through or ceiling support box). Everything past that is to be Class A chimney pipe all the way to daylight. All the manufacturers and the retailers have great info on what's available and how to properly install the flue system available on their websites. Rick
 
Ask your local hearth shop if they carry SBI single wall pipe. It's my favorite, 22 gauge welded seam and it has a really nice slip pipe system. So you won't need to cut it. The way they designed it allows it to come apart easily, even after there is some build up in the pipe.
 
I bought hardware store single wall for the shop stove and it is doing fine for now but I recommend you find the better stuff as listed above. The hardware stuff isn't super cheap or anything, only a small upcharge to much better stuff that will not only last longer and be easier to assemble.

Welded seam would be awesome.
 
I was quite impressed with the SBI pipe once I got a chance to see it in person. It's well made.
 
Stainless steel " All fuel" insulated - double or triple is the best, Stainless inside's with galvanized outer wall is the cheapo, you get what you paid for with longevity
