I have to say that, apart from the very dodgy headstock, i think this guitar looks quite edible. mmmm.
I think that on an unusual body shape like this, a slightly more reserved character is more appropriate and appears more refined - 22 frets is just so much cooler than 24; nothing wrong with a good quality rosewood board either. Those inlays are nice too - no ugly ESP thing on the 12th fret like most have.
The ESP model is, as has been said and repeated, of higher quality materials and workmanship than the ltd. Not sure if the ESP is still Honduras Mahogany, but if it is, that alone would raise the price tag considerably. The attention to detail seen on the ESP will be much higher than on the ltd too - hand-made guitars take a comparative lo t of time, which, obviously, costs money.
Another reason for the price difference is the way guitars are priced. If you drew a graph of guitar price against 'quality' (yes, a bit arbitrary i know), you would see the gradient getting steeper and steeper - that's just the way guitar pricing works.
