if patient, shotguns can be found cheap....and for some reason....in our areas, shotgun shells have not been effected by the ammo crisis...they are everywhere and the same price. in fact, my shotguns are the only thing i have been able to bring to the range in the last few months, due to the ammo shortage.
the shotgun is the most versatile firearm. from hunting, to range, to skeet, to HD....i feel everyone should own 1 shotgun. you can get a good shotgun relatively cheap and shoot it pretty cheap as well. (bulk shells go for apx $20 for 100).
basic pumps go between $200-300 new generally. decent pistols and rifles are few and far between at that price.
again, if you want to own guns...imo everyone should have a shotgun.
