You might want to give this AeroGarden 45w one a try. The price right now at $75 is as low as it has been, I might pick one up myself.

In the past, I've use the 30w version that is part of their hydroponic unit to successfully start tomato seedlings.
There's some cheaper Chinese alternative for sale, but most are pink/red tone. I like the fact these are white so less chance of a SWAT team busting through my door mistaking my tomato seedlings for cannabis.
