There you go again, another LMS of which I didn't know about. What I can't understand is that you are not prepared to pay for a free open source Moodle, yet you are prepared to consider paying for an unknown commercial LMS which does cost money. It doesn't make any sense.
If you want to keep your budget low, use moodle, browse and lookup the additional plugins within moodle, search for all the open source desk top software available that will be useful for you in e-teaching, and you wont need anything else but moodle.
You only need one LMS, so you might as well use the one that's best known, and has the strongest support, and that is moodle. Search best open source LMS on google, and let me know what you find in your search?
