Of course, a new(er) door is always the way to go, but finding one that's local and in good shape for a decent price ain't as easy as writing it down in a 3 second post. I'm not so sure a replacement door is less expensive, that might be true only if you can source one locally. Shipping just the weight of a toothpick is very expensive these days and even finding a door locally for a 30 year old niche car is getting difficult.
IMO, this damage looks fixable - not only rather quickly, - but in a cost effective manner. Check w/ your body guy first to confirm, it's difficult to be sure with only one pic. Not saying you shouldn't try sourcing another door, but that might be many months away and may eventually cost triple the repair w/ shipping or travel costs thrown in.
