A friend just mentioned that Amish heater advertised in last Sunday's LA Times. A friend of his family's in the East has had them for a while, likes them and they are supposed to be low wattage.
Interesting you should mention this. My mom (who doesn't have the internet) called me about them. Her friend got one and loves it. (She hasn't received her electric bill yet, but it warms the room)
I went online and looked for reviews. It seems to run about 25% positive and 75% negative. Many of the posters said this fireplace puts out the same heat as one of those portable electric heaters. If you convert the BTU's to wattage, they are the same. You can get a nice electric heater for $30-$60.
My mom saw her friend's heater and said it seemed well made (this from a woman who buys cheap stuff, so not sure she's a reliable source). She also said the picture of the fire on the front looked quite real, and when the woman put the heater on high and got really warm in the room.
I recommend doing your own online checking into this before you spend that kind of money. I believe they start at around $300. My mom called them and they told her her "coupon code" had expired and wanted to charge her $450. She said they were very hard sell and she ended up just hanging up on them. That's when she called me.
I have a small portable heater (Vornado) in my office and it works great. Cost me about $55, but of course, there's no ambiance of a fireplace.
Good luck!
