Well, the PGM301 is almost 2 times the price of the DK2M, so its quite unfair to compare them both. And the Jackson has a LFR while the Ibby is fix bridged. And the Dinky bolt-on joint is quite a bit more noticeable/bigger than the PGM301.

What do you want to play? If you're more into shred, get the PGM301. More suitable pickups and body wood. If you're more into metal/rock, the Dinky would be a great choice already.
