Hi, the link that you send is for the standard wrench without the extension bar. This is the part that I have which lists on tooltopia for $445:

Btw you want the extension bar for the extra leverage to break loose 440 ftlbs. I'm a skinny guy so there's no way I can break it loose with the standard length bar. Even with the extension bar it still takes some work.
I can't do $250. Sorry.
