I am considering purchasing a brad nailer and air compressor or a combo kit. I think an 18 gauge brad nailer will be sufficient for my needs right now but would like a compressor that I can use for bigger nailers/staplers in the future without having to upgrade. 99% of my projects are home improvement/DIY (shelving, bookcases, cabinets, molding, etc.). Any information regarding brand, style, pros/cons will be helpful. Thanks in advance for your help.
