It does seem pretty affordable if you think how much your shoulder rig is going to cost you in a professional setting.
If your looking for a cheaper solution you could go for a small SD monitor like the Ikan v2500 and mount it with a bendable arm and a loupe on it. Obviously this method isnt as high quality for shooting but on the t2i your watching an SD image on any external monitor while recording which for me makes pulling focus pretty hard.
The Ikan monitor is pretty cheap though. All you need next is a power adapter for it and a way to mount it (it has a 1/4 20 in the bottom so it shouldn't be hard)

The only problem i have left is to find a loupe that will fit nicely on a 2.5" screen/
