oooOOOOOOOooo - Very organised 
Scopion most HPA system will work with most E-Blade Cockers. They all do basically the same, that is supply the cocker with air at around 450 psi ??. The problem is that the cocker wants a lower psi than what most air system give out, so most people use a 2nd regulator (than on the bottle), such as a black magic or an ergo reg to reduce the pressure going into the e-blade.
So, if you have a 2nd reg on the e-blade in question you can pretty much attach any HPA system to it !
As Cesarbasanta said:
Low price range go for a preset (preset output)
Midium price range go for something like a Nitro Duck X-Stream ( these are an adjustable output regulator but are screw in system so need an ASA to attach to the marker)
or
'Money to burn' range go for something like a Angel AIR or Flatline (adjustable and not screw'ing's - they attack to the bottom of the trigger frame)
I'm not saying any are better than others, but a good HPA system would be high flow & consistent, and the systems stated seem to be better as these two things for the more money.
Hope this helps
