I've already worked out the costs for DIY Co2... And DIY is only worth it if your tank is a 2 foot(standard) or less. In the long run, with a tank the size of yours Karl, in less than a year, DIY Co2 will end up costing you more than a pressurized Co2 system. That is alot of yeast bags per week my friend...
And also, buying 7 of those things u mentioned above, first of all, they don't effectively produce Co2, and second, a pressurized Co2 system would cost less than 7 of those...
My opinion, if you are only going to lightly plant it, don't put Co2 in at all, the fish will provide enough waste for a couple of plants to survive, but once again, you will not get the luscious green received with Co2
