I really don't know anything about them. I saw one for sale earlier this year, and the ad said it needed a new barrel, and some work. Now I just saw another with really nice tang sights. So in case I bump into one, are they worth owning?

Yes, worth owning.

They made a short barrel carbine, and a long barrel rifle. The long barrel is heavy, but fun to shoot.

Go for it.

They make two versions of the "yellowboy" .22. There's the one that's like the Henry Arms .22, which is a reduced size version of the '66 yellowboy (current Uberti's have nickeled receivers), and they actually make their Winchester '66 in .22LR as well. Either would be a delight to own, but the latter will cost you about double the former.
