Get the ram that u already have
If it's a transcend, get transcend...
although it will be hard to find an identical stick if it's Hynix, but try to find an stick same as ur current one.....
if u purchased ram with any of ur friends, i mean u 2 purchased ram together, and he has the other identical 256Mb in his comp... use that and get him another ram....
otherwise, I'll say corsair value select is still better than all that's available in india
