I just sold a pair of KEF 103.2 speakers on Craigslist for $300. They show up every now and then in that ballpark. I sold them for my aunt, who bought them new in the 80s. I hooked them up before selling them and was blown away, and would have been tempted to keep them in my second system, but I had literally JUST bought a pair of white KEF LS-50s for that system 2 months earlier. Not to mention the WAF of the LS-50s is a lot higher than a vintage pair (and the 103.2s were about twice the size of the LS-50s--not what I would describe as "small" bookshelf speakers.
I loved the KEF sound back in the 80s, and those were high-end KEF bookshelves at the time. For the money, I was truly blown away, particularly from the middle frequencies up. Bass not super tight but there was plenty of it for a bookshelf speaker. Midrange and treble were sweet and detailed. You might give a pair a try and at that price, you're not investing too much and can always resell them for about what you paid.
