Any way to convert mp3 files to .wma?

[Nekusagi]

I've been downloading quite a bit of various J-Rock lately. Unfortunately, I'm using Multiply, and the majority of files (actually, ALL of them) have been MP3, which has been eating up space on my player. I just bought a memory expansion (mine's a 1 GB Sansa with a Micro SD slot), and I've got a lot of room (it's 1 GB), but I'd like to be able to have room for my other music, and .wma's are comparatively smaller, which is nice, given some of the stuff I've downloaded has huge mp3 file sizes (somehow, a Malice Mizer album ended up being 130+ MB, compared to an average size of 50 mb for 10 or 11 tracks).

Thanks for your help!

It has nothing to do with the different codecs and everything to do with bitrate.

Here's a link to a program you can use:

Has a trial option for 15 days, though it's something that's really useful.

have you tried windows media encoder? Also I'm sure the player would do it, but the movie maker also does it (it may lock them at 128kb/s though). Converting to wma for free is easy, its the other way around that gets more tricky.
