H Val,

Check around. It might be possible to have that repaired, by replacing the front element of the lens.

I have no idea about parts availability or cost (new or used from a donor camera)... and don't know how much work is involved. Often this type of repair on an older camera is cost prohibitive. But sometimes it's surprisingly easy and affordable. You'll never know unless you ask around.

If it isn't cost effective to repair and you end up shopping for new, don't toss the old camera. You might be able to sell it "for parts". Probably not for much money, but better than nothing.

It probably won't work with macro, but an old "fix" for scratched lenses was to fill the scratch with black ink. This prevents flare from the scratch and, unless the scratch is large, can even make a scratch pretty much disappear in images. However, this trick works best with longer focal lengths and less well with wide angles, small lens apertures and close-ups, in particular.
