Have only ever used chips so far, and always from Bunnings. They actually have a bit of a range there nowadays, bags of hickory and then mixed boxes, hickory and mesquite for beef and lamb, apple, cherry and mesquite for poultry and pork, mesquite and alder for seafood. $10 for 600g, probably not the cheapest but good enough to get into the game and experiment.
Most of the times it's quite easy to separate the individual wood types if you look them up on google images, so you can try individual types, 100% cherry for example, to get a feel for the different outcomes.
Usually use a combination of soaked and wet, depending on how long I cook. Have only ever smoked in the weber kettle, can't really see why a dedicated smoker would be any better, apart from the fact that you can fit more food in there per session. Is there something I'm missing?
I use either heat beads, robot turds or lump charcoal as fuel, or a combo of either two of them or all three.
EDIT: a quick google tells me that Bunnings actually used to have a much better range including pellets but have since downgraded.
