If you can afford to smoke you can afford $90. I quit smoking when I got out of the Army in 1971 and found out I wouldn't be able to buy cigarettes for $1.70 a carton any more. I almost passed out a few months ago when I saw that $1.70 would only buy about a third of a pack.
If I was still smoking, I probably wouldn't have enough money left over to fly.
All this said, I think we all know why the OP wants a cigarette lighter in the plane. I solved the problem with a rechargable battery pack. That thing will run however many GPS's, IPhones, IPads, and whatever other gadgets you want to hook up for probably weeks. It weighs six pounds and gets the job done.
