Online Security Guard Training? Legit?

I wanted to take on a part-time job and since I have some security experience from a few years back, I thought I'd go for it.

Anyways, has anyone done their course via online with any company? I found one Security company called Blue Knights Security offering it for $129 online and they are listed on the ministry website.

Anyone have any feedback on these online courses? Or should I just fork out the $280 groups like Paragon are asking for?
