The technical things I look for in a pipe now are:
1. Draft hole placement - make sure the hole is centered coming into the bowl and that it isn't coming through the chamber (bowl) wall ABOVE the bottom of the bowl. I have a few pipes like this and you can't smoke your tobacco to the bottom.
2. The tenon and shank (I don't have a diagram of a pipe to help here. Sorry. You'll have to find one somewhere on this site) are snug but don't require excessive force to get the two apart or back together.
3. The pipe cleaner test - put a pipe cleaner through the air-hole in the stem and make sure it goes all the way to the bowl (a small amount of fiddling to get it there is OK. If you really have to play with it to get it there, move on to a different pipe). NOTE: if the pipe uses filters of any kind this may not be possible, but then, it shouldn't matter as much since this usually is to get rid of excess moisture. (Hope that makes sense)
4. Probably the MOST important- You LIKE if not LOVE the way the pipe looks and feels. If you don't you won't smoke it.
Addendum: these aren't hard and fast rules, but they should help steer you to a better constructed pipe.
