SVN in .NET for a small project

I manage a small project for a client I want to be able to start using SVN to give a better service from multiple computers, I would like a SAAS solution as the project is to small to ask for a dedicated server in my client's company.

What is the best SVN hosting service/VS2010 plugin you recommend

Thank you

PS. Other ideas for a solution of my problem are welcome I am new to this way of working (SVN)
