Which hardware to use for sliding wardrobes

I am getting my wardrobes with sliding doors done by a carpenter and as you had suggested I asked him to get it done with the top hanging mechanism. But he came back with a wheel on the bottom mechanism and said that this will be durable. Something like in the link below:

I found one alternative in EBCO. Link below:

But the local shop here do not have this fitting. I am trying to check it from the main dealer in Bangalore.

The Hettich ones are out of my budget, so can you suggest any other make for this fitting which is not too heavy on the budget

Murali,
Ebco is cheaper than Hettich. You can look for any of their dealers online who will be able to source it for you. Their website should have the phone numbers.
