Guyz, jz wanto confirm.. this rim is 24 holes right ? anyone know how much is 24 holes rim cost ? ?

Why are you changing your rims? Yes, that's 24 hole but you won't find it locally!

Our local bike stores or rather the main importers don't import just rims, those who brings in 20 inches are usually the whole wheelset. ( Hubs, spokes and rims, all assembled). Also not many local bike stores can lace and true a wheelset properly.
As for cost, it can run to 1.5K for a Kinetix to a few hundred for the Weinman D17 with Novatec sealed bearing hubs. If you have contacts in USA, maybe you can check out wheelsets for recumbent bikes and it's usually sized 406. There are actually many types, it just that it hard to find it locally.
I see many 20 inches rims in Taobao and very cheap too but have no confidence in ordering them. So, I rather pay more to see the product first before getting it. I paid RM450 for my Weinmann D17 with Novatecs. When I got it, the lacing seems OK but when I rode for the first time, the rims ran out of true. It seems the person who laced it winded tight on one side and loose on the other. I have to loosen every spoke and adjust all over again. So, be prepared to pay for re-truing the wheelsets. Sometimes, the dishing is out, means the rims are not centered to the bike frame. This affects the V-brakes.
If you are looking for nice wheelsets, I have posted one in the earlier comments. Johnny (MY Bike Shop) sold 2 sets already and there's still another set left.
