A lot is going to depend on your lighting and your water parameters.

Ideally, a pressurized CO2 system is the way to go. Pressurized is very efficient and accurate, however, the Hagen unit is a good way to get some CO2 into your aquarium (better price here, BTW http://www.thatpetplace.com/Products.../Itemdy00.aspx). The Hagen unit can be a bit undersized on a 40G. Particularly on 40G with a lot of light. Something similar can be rigged up with some empty juice bottle, some ingenuity and one of the Hagen bubble ladders. The juice bottles will accommodate more sugar, yeast and water and make DIY CO2 injection into your 40G a lot easier and more efficient than the Hagen unit.

Some info on your lighting would help.

The only real advantage of the going with the full Hagen system is aesthetic, however, my brief flirtation with it was that it's rather easily broken, the mounting clip for the cannister broke, cannister fell and broke with a minor eruption of hootch.

I then just hooked the ladders (which works very well) to a good ol Coke bottle affair, now I use them with pressurized.
