Its has been stated that Agriya products are expensive, i have personally experienced with their script.
Price is not only factor to determine the product, it matters their deliverable value & product quality which distinguishes themselves from other competitors.
The most important factor of their solution is stability, Despite and the system performance will be too good even in peak load conditions with high volume of data.
Just visit Agriya site , and watch in to the demo … you can feel the difference.
