ahh thank you all for your great responses!
well the problem is that i dont have a credit card right now ( always been ok without it). In fact each time i surf the web, i'm amazed how much you americans are using the net for commercial transactions... since here nobody is doing that, in Québec province ( i think that quebec has the lowest rate of electronical commercial transaction in n.america).
anyway, i keep those infos in mind, for the time when i ll have a credit card, or ask a friend or family...
I dont know if im ready to invest in a big co2 machine anyway, since i like low tech, am a newbie, and with only 2.1 wpg and 2 hagen ladders + flourish excel, my plants are doing ok. If the carbo plus was going to be good, i would have bought it, cause its really cheaper... but now that you told me that...
cs:'' There are many veteran Canadian hobbyists on there eh. <-- gross misuse of the lingo eh? ''
well im from quebec and english is my second language, so i dont really know the local expressions of english canadians
i learned not so long ago that they were using the '' eh'' all the time.
