Well, LightBulb costs $31.50 Gile[s] $39.95, so the difference is not that big. And, doesn't LightBulb use the YAL lightmapper?
Actually!! Gile[s] cost $51.85 in US dollars. You must be looking at the english pound amount: &39.95
You might want to check it again, because that's what I paid for it from my credit card.
