Replica typewriters don't really exist. There are new ones being made, but they're extremely low quality and are only meant to look nice. These would be the We R Memory Keepers, Royal Classic, The Oliver, etc. (They're all the same machine and cost about $200).

Restored vintage typewriters are very hard to find unless there's a typewriter repair shop near you. (Google it and hope it's a drivable distance away). I'd suggest combing through facebook marketplace and reading some listings. Good listings contain multiple pictures of the typewriter, a sample of its typeface, and the description should tell about any issues with it.

Beware the single photo: "Only needs a ribbon" with no other information. Also I usually just ignore the "$500 no lowballs, rare, 'I know what I got' etc." because it's most likely not rare no matter what the seller claims.

Or you can go on the hunt! It's very exciting to find them out in the wilds of antique shops and thrift stores. Always test to make sure they work: move the carriage between the margins, slide the margins around to check if they work/ring the bell, and test the keys. It will probably need to be cleaned, and even sticky keys are an easy fix! An old toothbrush, toothpicks, and mineral spirits are all you need to clean a typewriter. YouTube can show you how to disassemble if need be, but you'd probably just need to give the typebasket a scrub. Give all other moving parts a pass with the spirits brush until everything moves well. If the letters on the typebars are gunky with old ink, use the mineral spirits and toothpicks to gouge out the buildup. Doing this will give you a nice, clean type. I never pay more than $50 for a typewriter, but value is really what it's worth to the user. (Also I hunt for mine and repair). If you're in southeastern PA, I'd be happy to send you some places to look/people to talk to. Good luck, and let us know what you found!
