First, I would build a cheap wooden canopy if I were you. Then, you can:
1. buy a cheaper set of powercompact lights of the auction site. like the 48" 220 watt Jebo (I have one and don't have no problems with it, though some others don't like it). this would give you 4 watts per gallon which would PROBABLY be enough for a condi anemone, but not any anemone that clowns host. it would also be good enough for SOME corals.
or
2. for $150, you could almost get 2 of the Jebo units, take them apart and fit them into your canopy, which would give you 8 watts per gallon, which would be good for about anything.
or
3. buy a retro VHO or T5 kit off the auction site and build into your canopy.
option 2 will probably give you the most wattage to keep what you want, but will also be the most expensive when you add in shipping and replace Jebo's "blue" bulbs with real actinic bulbs. as far as the canopy, you can build one for well less than $30.
