moving to svn?

It also costs a lot, probably more than any version control software
out there. Although I cannot disclose how much we pay for it (and we
have an academic license), if you came up with a figure in your head
and multiplied it by two that would probably be far less than how
much it costs to pay for a 1 year lease of BitKeeper. That said, it
is a great tool.

I've heard prices on the order of $1300USD per-developer per-year but
it likely depends on the number of developers and that number is from
a year or more ago.
