I'm not sure if this would be helpful because most of the websites with local offers are unfortunately only in Polish.
Our craigslist example is
www.olx.pl,
www.gratka.pl
Ebay-like auction service:
www.allegro.pl
I live in Gdynia which is in Pomorskie voivodeship (similiar to USA states).
Well it's still possible to just use search engine with some brand names and maybe something interesting will pop-up. If you need help PM me, thanks.
This is what I found so far:
1. Raleigh Pursuit 25" frame, not sure if it's CRO-MO, propably regular steel (
Raleigh 18-23 Steel Tubing that's what seller wrote). Very cheap around 70 pounds including shipping.
2. Some Bianchi unfinished project. Unfortunately frame seems to be 22".
3. Gazelle Reynolds 531 24" size
4. Same as above but 23"
5. Koga Miyata Roadrunner 23"
6. Some Raleigh Reynolds 501 22,5"
7. Univega Alpina 5.7 size 21" but I believe it's MTB frame?
8. American Eagle Concorde 21"
9. Trek 830 complete bike for around 100$ which could be a good base for future modifications and it's located in my city. 21" frame
+ Lots of interesting frames from this seller, unfortunately all in Polish, I can help with translation.

That's all I could find for now, as you can see it's hard to find interesting 25" frame, will keep searching.
Yes I'm going to look into ebay.de soon!
