I picked up 4 michelin XM1's for a good deal last year.
He stocks major alloys brands too.
P.S. U can refer my name. His shop is on greams road.
I was planning to change my stock steel wheel to alloy wheel, after going through this thread went to tyrestore and got that changed. Deepak (Tyrestore) suggested me to go for Auro for my Ikon. I gave away the steel rims to him and the final cost came to 20K (including Rs.800 for aligning and balancing the wheels). Attached is new alloy wheel image:
