A peek at the TX-SR343 Amazon reviews comes up with 18% 1-star (out of 5), that's a little high for my comfort, so it depends on the service of your local retailer, because if you have to send the "boat anchor" (I call receivers) back, can be a (relatively) major expense+hassle.
Honestly these days, seems to me if you are buying entry-level, you don't know what you are getting. If I were in your shoes, I may think of used market, eBay in Singapore? at least there the box is already been tested, if the owner haven't had a problem with it, say for 1 year, the chances are, it will stay healthy for a few more years. Just throwing you another option.
