Does anyone have any suggestions on what to use to make a realistic campfire.

You could always make up a flicker effect quite cheaply yourself!
Place a neon fluoro starter in series with an incandescent globe. Fitted in both Active & Neutral circuits.
It is more effective to produce 2or 3 light circuits, giving differing flicker timing.
F convince mount the incandescent globes on a suitable plastic electrical Junction box, with their lamp fittings.
Connect a pigtail lead with a male plug top.
This unit can be run via a dimmer circuit & gives a realistic effect when starting & building over period of time too a brighter fire.
Use different colour globes or mixed gels, also you may
want to add a second starter in parrel or series with the other to modify the flicker circuit.

I really appreciate your suggestions.  Thanks!  Could you please elaborate on what you mean when you say surround the lights with gels?

I just did a roaring fireplace fire for Scrooge.  We went to Spencers gifts (any big mall should have one) and purchased a false flame pot.  It was a small fan that blew pointed strips of silk up.  This unit had small lights under it to illuminate the silk strips as they fluttered.  I surrounded this unit with pieces of firewood.  One pet peave of mine is when people do this and the firewood looks unburnt.  At least the ends of the wood near the "flames" should be burnt.  I did this by simply burning one end in a fire and then dunking it in a bucket of water.  The charred end and the flame pot made a very convincing fire.
