Unearthed Sampling is a super cool company for inexpensive quirky sound design and instruments. Weird stuff you won't find anywhere else, and worth knowing about. They are all created by video game composer Rich Douglas.
I have Spaceology and have considered Forgotten Sounds, Esper Synth (beautiful Blade Runner Sounds) and their Legacy Bundle of 9 libraries, including Scrape Orchestra and Hum Pad (both in this deal), Fistful of Tension (a Morricone-inspired guitar), Soft Tension Hits, and The Cello of Damascus (cinematic bowed guitar), and others.
If you like the unusual, it's worth checking out Douglas's sitehttps://www.unearthedsampling.com/instruments
The normal price for each individual library is always very low and there are frequent store-wide sales at Kontakt Hub.
