The reissues are KonamiStyle exclusives, so you'll need a proxy service to buy them (basically someone in Japan who'll buy it for you, then ship it internationally to you once it arrives). I have them both preordered via Yokatta
, but I don't know if they'll still have any slots available. Can't hurt to shoot them an email to ask, though (including a link to the konamistyle store pages would probably help you get a quick response).
Eukrante was 5400yen, and Altlene was... actually, I have no idea exactly how much she was, as I ordered her at the same time as the fencer repaints, and only got a combined total. Note that you if you ordered them together, you'd probably pay slightly less than 5400yen for Eukrante, by spreading the proxy fees over the two items (going by the prices listed for them individually, my order of the fencer repaints and Altlene would have totalled 21750yen - ordering them together cost 20225yen)
There are other proxy services, too - RiderProxy
are a couple I've heard generally good things about. Never used them though, as I've always been able to get whatever I wanted through Yokatta.
