yeah, im the process of replacing my 3 bar lights with 16 CFL's which should help a great deal, if the price turns out to be over 200 .....i'll get a nice hid setup, im already planning on buying one within the next month or so for my flowering setup. the bar lights will be used on the sides once i get my top lighting figured out. This is what i've spent so far.
$20 for the mylar, They come in 3 dollar packages, I got about 6.
$25 for the main fixture and 2 40'' bulbs.
$20 for the smaller fixture and the 20' bulb.
$15 for the shop light fixtures and reflectors.
$15 for the CFL's for those fixtures (27w)
$10 worth of duct-tape and Nylon rope, Rope being used to hang the fixture and tie the 2 curtains in front closed.
