Thinking of making a base station: Go 12v mobile or buy a new/vintage base?

Looking at possibly getting back into CB and I might want to set up something in the large shed I have. What Im curious about is, should I go a mobile 12v or get a dedicated base station one? Ive seen vintages that are supposedly good like the Uniden Washington, Cobra 2000 etc. or maybe new?

Looking for suggestions!

Thanks!

Will be used solely as base only.
