Unless I had a specific need for a .41 magnum, then I'd stick to a .44 special, especially if you think you might buy a .44 magnum in the future. (I originally looked at several .44 Specials, but finally settled on the .44 mag, since it's more versatile.)
I've almost bought a .41 magnum, but what stopped me was limited projectile selection. There's nothing wrong with out of the ordinary cartridges, but they're easier to love when the projectiles are readily available. For instance, I enjoy shooting the .38 super, which can share projectiles with the 9mm, and those are relatively inexpensive.
