Get 4ft long T8 or T12 shoplights (I prefer T8s). You can get them at Wal Mart for cheap, or Home Depot for about twice the cost. You're better off paying for the best brand fixture you can afford (Home Depot/Lowe's). I've found that the cheaper fixtures tend to blow out over time, and cost more to fix/replace than I would have spent if I'd bought decent lights to begin with. For bulbs, go with half 4100K and half 6500K bulbs. This gives great color and awesome growth. Keep in mind that 2ft fixtures are more compact and easier to use in a small growing area, but 4ft bulbs are way way cheaper! I've had some trouble with Mexipings and D. adelae under very bright light, so try to keep them at the edges of your growing area. The capensis and most other sundews will take as much light as you can give them, and still beg for more.
If you're looking for the best solution, check out Aquarium Hobbiest Supply (ahsupply.com). They sell pre-made wooden hoods and fantastic compact fluorescent kits. Their kits are also great for retro-fitting existing fixtures.
If you want more information, just post questions here. I've done a nerdly amount of research into lighting for CPs, orchids, and aquaria. I'll answer anything I can, and try to help with anything I can't....
