Subversion from Windows

I have svn working on my Linux box, installed on Debian Sid. I need to be able
to access it from a Windows laptop at times. As the Linux box is accessible
via ssh, I thought that svn+ssh would be the easiest access method. When I
try it, however:
 svn list svn+ssh://myserver/repos/project

I get the error message

 svn: The system cannot find the file specified

Well, 'duh, I think. Windows doesn't have an ssh client. I then thought, I've
got Putty, and putty myserver will start an ssh session. I then copied
putty.exe to \winnt\ssh.exe (effectively creating a command line ssh client).
I tested it by entering ssh myserver. It connected cleanly. I then retried
running svn with the svn+ssh protocol. Now I get a "Wrong port number" error.
Obviously putty can't serve as the ssh client for this.

How can I connect from Windows? If I need to do work server side, please refer
me to something to help me with the setup as I admit ignorance.
