First of all, I have no experience with the pre-built CO2, but I would not expect anything other than a pressurized system to deliver significantly different results than a DIY system...
As far as a reactor... it appears that bell reactors do not have much impact, I personally feed my CO2 to the water intake of my filter, this seems to be the most favored approach.
In regards to the mix there are many references out there.. google is always a good source... try this link first and go from there.
The second hit on the previous search (http://www.qsl.net/w2wdx/aquaria/diyco2.html) is one of the best articles on DIY CO2 I've read. It should get you going... come back with any specific questions.
