Wanted to buy tplink archer D9 modem router but a lot of the sellers came back to be that it's a discontinued product. Can anyone please recommend some other good model?

Over budget already. I think will keep within rm600 and below. But yes I do need that cause we have multiple users all day. Phone , tabs , laptop and pc. Also looking for ones with guest network and bandwidth control features. I thought archer d9 is still not that old , but seems all seller replied it's already discontinued.
