Low costs are perhaps the prime benefit of offshore outsourcing. You can get work done at a fraction of the cost that you would have to spend locally, while getting better quality as well. Because of the differences in pay and standard of living that exist between Asian and Western countries, labour costs are much lower in Asia. On an average, you can expect about 60% cost savings if you outsource to countries like India.
The low cost has no impact on the quality. Its cost effective; not cheap.
