I was looking at this set up from Gardeners Supply...

My question is, when I have to replace the T-5's do I have to get them from Gardeners Supply or can I just get any T-5?

I was also looking at making my own set-up to lower the cost, but if I get good T-5 lights and fixtures, nice looking shelving etc, it will come out to close to this cost, but not as high. I do not want to get something I cannot replace with any T-5 I want.
