Here is Sri Lanka you can go for Kathy and Beer Bates book. Its the Best for 1.4, as i have heared there are no resources yet solely for the 1.5, what u can do is, get the K&B's 1.4 book. Study them to end, then findout what are the differances in 1.5 ( new stuff added to 1.5) cover them up using some other material. U can buy K&B book for Rs.900 with the CD from Expographics.
Follow the above if u r taking the exam soon. Otherwise u can wait till a resource is release.
