I work at a hardware store, and at my work if a new employee doesn't know what ABS pipe is after like 2 weeks, they would be gone pretty quick. Someone said that the people at local Home Depot said they don't carry it, but I cant see that being possible. Unless somehow its against plumbing codes in your state (which would be rediculous because its the best thing for many applications), they have it.
Comes in 1.5, 2, 3, and 4 inch sizes, and almost always in 10 foot, straight black sticks. If a moron Home Depot employee brings you to a section of rolled black pipe, tell him to try again because thats underground poly pipe, not what you want. Also, even if they dont have the same brand of ABS cement (I think Oatley's was mentioned), I'm sure any other brand is going to be the same stuff. Just make sure you get the can that says just for ABS, not the PVC/ABS multipurpose stuff.
If you dont need too much, you could just buy a couple elbows and not have to worry about big sticks. Also, at least at my work, all the connectors are solid ABS while the 10-foot sticks are kinda bubbly on the inside to reduce weight and increase impact resistence, so it would probably be easier to get a larger volume of paste with fittings because they can be shattered easier and more of the volume is plastic than air. 1.5 or 2 inch elbows are the most popular type of fitting, so they probably have the best cost/weight ratio.
Someone asked about getting abs sheets, and a quick check at McMaster-Carr showed a ton of different sizes/thicknesses and maybe even colors. If its not on your favorites list, it should be, www.mcmaster.com . Thats all I can think of, except that *shameless plug* if you live near a Do It Best hardware store, give it a try if you dislike the way Home Depot people know pretty much nothing and how they are always understaffed. *end shameless plug*
Hope this helps,
