[US-NV] WTB DSA Scientific and XDA Keyset

Good evening. I am on the hunt for a couple keysets. First, looking for DSA Scientific, at least the Alphas and Ortho kit. Would also be interested in the Numpad and Novelties kits as well.
The second set is pictured below. I owned this set years ago and couldn’t remember where I got it from but found it on KBD recently.

Thanks in advance for any offers!
