For KL, I can't really remember the shopping centre I went to but there are 2 main shops there that have reasonably good price. If you head down any Isetan or Metro departmental store... you should be able to get some latest toys at a reasonable price too.

I'll get back to you on one famous shop in KL too but it's quite a distance away.

Cheers
