Dear Sam,

 As you've already wrote, it's very hard question, because everybody wants to spent his money as well as possible. In this case I can share you my best experiences with http://www.Training-Online.eu. I used in the university and now I use it in my own company to educate employees.

 The greatest aspect of this E-learning platform is that you don’t have to pay any fixed monthly fees and there is no initial investments. That means you pay only for assignment to the course. Despite this the quality of the services is really high.

 I’m sure that the thing you’ll appreciate the most is the security. – All data are here kept in full security and if you’re not an authorized user with access to the e-Learning Management System, you’ve no chance to go there.

 I hope it’ll help you.

Let me know and take care.;-)
