Hi, I'm new pianos and I've searched around here in Sabah, East Malaysia.

I've spent these 2 days and came down to a few list of selections.

Diapason, 124cm RM 6500
Victor, 133cm RM 6000
Appollo 124cm RM 6000
Kawai KU2 RM 7500

I'm not very sure of the ages. Will get those info soon. But they sound good for me... So... I'm really considering these.. especially victor... Do you think is a good choice? Besides, what are the general information i should get if i were to shop for a piano?

Be sure to check a thread about "adult beginner in Singapore", the folks who post there are closer to your region and may have some good tips.
Also can search Malaysia as well. I say this because age and condition of each will be key and folks closer to you will have a better idea about these prices.
You may wish to click and order The Piano Book by Larry Fine, it has a section on how to look at used pianos for their quality. Or check the FAQ forum as well.

Well thanks for the reply and I'm on my way of checking those other threads...

But of coz... I don't mind getting more advice here anyway....

I've seen all the mdls.and manufactures mentioned on your list. Diapason is an older stencil of Kawai in the asian countries. Apollo is an older stencil for Yamaha in Japan and ?. Victor is an old lower level Japanese piano manufacture. Kawai KU2 is an old......Kawai mdl.
Don't they have any newer stuff ? These pianos are ancient.
