NEVER use acid core solder on electrical components. The acid will stick around and continue to eat into components and wiring well after the soldering job is over. Resin core solder can be had in various quantities, but I buy the one pound roll for around $12-15 which will be a lifetime supply for most folks. I use Kester brand 44 Resin Core solder in the .031 diameter size. This is about the size of mechanical pencil lead and works quite well for what you will be doing.
