need advice for good avr under $300 (maybe)

Check the Best Buy stores in your area as last year's HDMI 1.4 AVRs (eg. Denon 1611/591 and 1911/791) are on clearance at low prices, some within your budget.

I provided model numbers in my previous post.

Considering that you're in Singapore its gonna hard for us to find something in your $300 price range. Especially if you say those receivers go for $900+ over there.

there may not be anything in the $300 price range.

You're likely to get a better deal on last year's models and as your sources to purchase an AVR are likely limited .. why don't you do some legwork and provide a list of those in your price range and then get feedback on them.
