Looking for keyboard / synthesizer

I arrive in Hanoi soon and need a keyboard or synthesizer to continue my hobby.

It should have at least

- weighed or semi-weighed keys

- at least 5 octaves (61 keys)

- output to amp

I'd like some advice on how to get this. Is there a good music store in Hanoi? If I'd go for second hand, is there much of an offer and what are the best places/websites to look?

Thanks!

Hi Khorne,
There is one in Ngo Tram street. I do not remember exactly the number but you can find it easy because it is a big shop in a small street.

Thanks Ms. Tram!
