The guy behind svnrepository.com is also behind railsplayground.com. The $5/mo plan at railsplayground gives you a web host AND a free svnrepository account (1GB storage, unlimited repositories, unlimited trac instances, https access, use your own domain..). That might be the best value.
Rock solid. I've always had access to my svn repository and it's always speedy using it. I've been using them for about 8 months now.
For svnrepository, the control panel doesn't look that great, though =/. But you really won't use it that often, only once in a while to setup new repositories and trac instances (and users).
