If you only have $450 you should not be looking for a specific brand of light, but the most bang for your admittedly limited buck, which will really truly be the store-brand lights that inside sun has for sale. They're bare-bones basic and work just fine.
If you want to upgrade, you can do that by ordering the hortilux light bulb upgrade. It's not the brand of ballast, but the BULB that you should be trying to optimize, IMO.
