Check JoAnn fabrics or your local fabric store, they sell inexpensive eyelet setters that should work with several commonly available sizes (>1/8"). I repaired a torn eyelet on my pack with a 1/8" eyelet and gun found locally. For light duty fabrics most cheap options should work. Grab yourself a self healing mat also, makes work easier and cleaner. Are you running thin Spectra through the bag? Yes, they do sell 3/32" eyelets, good luck fidgeting with those tiny things.
