As for the MH set, u can get the item at SLT, kelantan lane etc. but u need to do the wiring urself.
As for the casing, u need hunt for it urself................ but it will be hard.
Razo,
DE bulbs comes in alot of brands......it ranges from $50-$150. Depending on your requirement.
But for me, im thinking of buying the BLV 10k bulbs. Was told that PR is selling $110 ea.
Fireclown,
To DIY DE or SE, it depends on ur liking and ur tank setup. SE are easier to DIY and do not need UV glass protection..
