As with a lot of things it is a question of money. If you can spare the money buy an original period piece - there is nothing better and there will be no need to upgrade at a later date. But as these originals are very expensive (compared to most other medals) one may not have the money for it - in that case you can either not get a PLM (do you really need one?) or, if you must have one but do not have the cash for the real deal, you can go for a wearer's copy as the best alternative. In any case be patient most things turn up in one or two years. There is no shortage of original PLMs if you have the cash for it.
