I had pete r. from this site build me a canopy, and I bought my MH retrofit kits from hellolights.com including bulbs for around $600 total. I dont have any supplemental pc actinics at this time but it should be only a little more to add them in. I found the staff at hellolights.com to be very helpful in helping me pick out which exact thing to get. I ended up with two XM 15K mogul (normal screw in light bulb type, as opposed to DE aka double ended) bulbs (because they are bluer and I dont have supplemental actinics), 175 watts each. for my 55g softy tank that's plenty. this year in sept I will add supplemental actinic pc or vho, and get the 10K bulbs so I too can view my tank with just the actinics on at dawn and dusk. I too hate too-yellow lighting. good luck and let us know what you end up with.
