I would suggest the Freehand One. It's a modernized version of an old school classic. It's responsive but plays really well.

I think it'd be great for someone wanting to cash in on nostalgia. You'll be able to go up and down and rock some cradles and what not. Plus it's got what we refer to as an organic shape (This is modeled after like, the OG organic shaped yoyo), so it's nice and comfortable in the hand.

Available on Amazon, comes in on budget, and like I said. It hits the nostalgia button right in the kisser. If you have fun but don't really go on any further, it probably won't make you mad when you find it in your junk drawer in six months. If you do end up getting really into the hobby it's a great stepping stone to learn basic tricks on and then you can always come back and we'll give you good recs for the upgrade.
