I use the REPTI-GLO 8.0 bulbs. They are anywhere from $5.00 to $15.00 cheaper than the Repti-Suns and provide the necessary UVB requirements (at least, they claim they do and no one had proven them wrong yet).
I find that the REPTI-GLO bulbs provide more ambient light than the repti-sun bulbs as well.
