PC - Insightful Holy Staff of Enchanting

Price check please....

Also can anyone tell me if the actual value (in this case 532gp) relates to the trading value of the item. I realise some items are rarer than others but is the actual value another go by?

Thanks...

Would it be better to salvage and place mod on a better req. staff ?
