I had the cheaper one last year. I didn't buy it from Narikaa but I believe my watch was probably the same as his. It's huge. I had 6 PAMs back then and I found I always picked up a PAM instead of the XXL so I sold it.
Obviously the "Swiss" and sapphire model will be better. If you think you're going to wear it a lot and you have the cash, spring for the nicer model. If it's going to be an occasional watch and cash is tight, get the one from Narikaa. Keep this in mind, too, if it's going to be a keeper you'll want to replace the cheap rep strap.
