The other possibility is the apogee jam. it is more expensive but i have read that it produces very good quality sound. it does not come with available software but does work with several. i don't have any experience with any of the software, so if anyone has some hands-on knowledge, i'd really love to hear your opinions. the cool part of the jam is that it has a pre-amp built into the plug. here's the link to the apogee jam:
