>>7919266The one in your picture is pretty good to begin with. It depends on what flavor of retro sci-fi you're looking for.
I went down this exact path in 2016 when I went through almost the exact same thought process. I've now got quite a big collection and am very happy for it.
If you want something large and you want it to be classic space then I could recommend:
https://brickset.com/sets/6980-1/Galaxy-Commanderhttps://brickset.com/sets/6985-1/Cosmic-Fleet-VoyagerThese are both great choices that are a bit different from the standard 497 set.
If you want something smaller I really like these sets:
https://brickset.com/sets/1499-1/Twin-StarfireThe Twin Starfire looks very retro-sci-fi.
https://brickset.com/sets/6891-1/Gamma-V-Laser-CraftA personal favorite.
https://brickset.com/sets/6931-1/FX-Star-PatrollerAnother great ship.
https://brickset.com/sets/6783-1/Sonar-Transmitting-CruiserThis one is great, has some really good alt-builds as well. I have it in one of its alternate build configurations. Also has lights and sound.
If you want to go with something post-CS then you can try out Blacktron.
A medium ship:
https://brickset.com/sets/6894-1/InvaderThis is one of my all time favorite Space sets.
You can also get the larger Renegade - it has a very unique look.
https://brickset.com/sets/6954-1/RenegadeAlso all the ships featured in the Space Police I line have a very sleek and unique aesthetic.
