I am currently using source safe for version control but need to move away to a more multi-person control system that has merging capabilities. I have looked at sub-version but cannot find and gui's for it that fits my needs. There is tortoise but that integrates to explorer but i would prefer a gui similar to source safe.

Can anyone recomend a free or cheap version control software that supports multi-clients and merging that has a gui of similar design to visual source safe.

Thanks.
