But for most people I'd just say, "Don't panic, wait for these guys http://truecrypt.ch/ to take it over, and you can get the binaries from there".
TrueCrypt remains secure, the software won't break today, but it just isn't going to be there in the future (they never overcame UEFI and full disk encryption for secure boot).
bitlocker is proprietary encryption from Microsoft, and if you're not running your own domain they will hold a set of "recovery" keys for you.
Meaning it's extremely likely the NSA has all your data.
The weird thing in this is that TrueCrypt passed it's audit. It is secure.
There are alternatives, but none have a UI with the same ease of use as TC.
I'll probably use tc-play or dm-crypt directly https://tails.boum.org/blueprint/replace_truecrypt/ as those can use the TrueCrypt format (in part proving the standard cryptography of TC).
