A tart warmer would be a good option if you're going for the scent - they are $2 each tart and they last seemingly forever. They smell much stronger than candles do anyway.
Try out AJ's Country Candles. They come in 8oz Mason jars for around $9 US a piece and there are lots of scents to choose from.
