Question about Model M's

im wanting to buy a model m. is the unicomp 96U1114 Model M5-2 the same as the IBM Model M? 

I don't believe the Unicomp models have the steel plate that gives the Model M it's heft and rigidity. Also, from what I've seen, people seem to prefer the Model M over the Unicomp ones because the quality of the plastics used are also better.

But, if you need the Windows key or really want it in black I don't think it's a bad purchase.
