Canon SX510 is cheaper and also lighter than those Bigger SX series cameras.It gives you a 30x optical zoom which is equivalent to 720mm with same CMOS sensor Canon Powershot SX50 HS camera has. But it doesn't have a view finder and comes with DIGIT 4 image processor (SX50 has a new DIGIT 5 one)
This superzoom camera is not an upgrade for Canon SX30 or Canon SX40 cameras but for those who have old Canon bridge cameras like SX10 or SX20 models this camera might be a cheaper upgrade than the latest model which is SX50. Not everyone can afforded a $400 even it's one of the best Mega zoom cameras out there so SX510 is cheaper but a really good alternative.
