I do not know of any handpans in a $300.00 price range. The inexpensive ones I've seen were all over $1,000.00, with anything remotely decent being at least $1,500.00. Prices generally range from between $1,500.00 - $3,500.00 depending on the maker.
You might consider an electronic one, or a tongue drum if you are locked in on that price range. Otherwise I would just recommend saving your money until you can afford one. If you do manage to find an actual handpan priced at $300.00 I would be highly suspect of it.
