That all depends on a lot. Both are older, heavy, loud, and lacking in anti-vibe, making their worth low. Parts are a real problem, too. In my area, you could have them for $20 each if they run , up to maybe $65 if they look primo. Sometimes you see saws like this almost free. I have a 1-40 (very similar to the 250) that was free for helping a neighbor clean up after a garage sale...he'd put $25 on it my sugestion and it didn't sell.
Ebay might get a lot higher
