puting a factory sunroof in a lx accord

i was told that it would be a whole lot more trouble to put a factory sunroof in a lx accord. i was wondering if that was true or if the companies i talked to were just trying to sell me there products. if anyone has any advice please let me know

It may be very expensive to get the factory parts
