I've got an electric "smokeless" grill. Doesn't get as hot as I'd like but it's not bad. Works pretty well with the thin cuts of Asian barbecue for cooking at the table indoors. I do potsticker style dumplings on it when I'm doing a big dumpling feed. You have to watch the hot spots and add some liquid for steaming with the lid to get things cooked through in a timely fashion. Also a little juggling of items so they cook through evenly now and then.
My favorite use so far was for a Guizhou Grill Pot dinner. Basically a grilled hot pot instead of broth, but not in the Dry Pot style.
