SoCal is a bit like Australia, but our rats are smaller and don't hop.
Rattle gun is common around here for any impact, air or electric.
What surprised me is that impact seems to be the best choice for a lot of "light" jobs I never considered using it for. Its still going to be a disassembly only tool for me "most" of the time, but the convenience of using one is pushing be toward buying a cordless 1/4" drive impact.
If I had it to do over again, I would skip the bigger compressor I bought and get all cordless impacts for regular use.
For assembly work, its got to be an experience thing. Try it and if it works keep doing it and get the job done faster, but for amateurs who won't be repeating the same jobs over and over, there is a lot of risk pulling the trigger the first time.
