$130 would buy a 1000w HID though complete, that's the rub.
Are you really unable to run any HID at all? Not even those bargain $20 150w HPS's because two of those would be half the cost and the same lumens if not more. What is the combined wattage on the t5 ballast(s) if it's around 300w also then the heat will be similar to 300w of hid, as in you really aren't saving anyting or gaining lower running temperatures or costs. HID will do way more lumens at half the initial cost and with lower long term operating costs. (those t5 bulbs aren't cheap and still they give less lumens per watt than HPS or Halides)
The only benefit I really see with the flouro's is the tubes last longer than hid bulbs before they drop off too much, but they're more expensive and you're replacing more of them so that edge is probably moot also.
