Agree with all on the Bandsaw. I have a Laguna 14" and it works great; however, I always go to my table saw for ripping and some crosscuts. I have a Jet standing drill press, Dewalt makes an excellent and affordable planer (DW735). You can upgrade it later to a Byrd shelix blade. Keep in mind that it is a 13" planer. I have a 8" Powermatic jointer and I love it but I also do others things in my shop besides building guitars so it comes in handy for building furniture. The planer and jointer go together.
Other equipment that is useful for building guitars is a nice router table and a great dust collector. I actually would put the dust collector first, An air filter is also a must have in a wood shop. Something not on your list is lots of outlets and lights for all that equipment. If your shop is humid, get a dehumidifier. Also get an air compressor. Great for clearing dust off tools and projects. Also can be used for spray painting. I won't even get into hand tools.
