I have the bubbleponics system from Stealthhydro.com, and I do agree that it would be eazy to get the parts for the system; however, the kit from stealthhydro.com takes all the guessing and/or questions outta the picture, everything is included to grow with and the price isn't at all outrageous like every other web site. I did plenty of searching and after tweaking for about 2 days on the question found their kit to be the best value. $250 for everything (lights and all) is worth the investment.
