Well, here's my promised review of the site.
www.japanvideogames.com -- Verdict: Good
I ordered my PSP from them because they had it at the cheapest price. After getting confirmation that my order was successful, I braced myself for any numbers of problems to arise. However, none did. A short while later, I was sent an email informing me my package had been shipped. Although the trackign feature didn't work for several days, leaving me anxious to know the exact whereabouts of my prized order, it shipped relatively quickly, and I watched (once the tracking feature began working) that it shipped about the country in short order, and arrived within little over a week after I ordered it.
Because my term was almost over, I didn't bother having it shipped to my dorm, so it wasn't until this past week that I finally got a chance to open the package. I wasn't happy that they didn't have more than a bubble-wrapped UPS envelope to protect my PSP box inside the shipping box, but the box was in pristine shape when I got it out.
As is usual with Japanese hardware, there was no factory seal on the box, but everything inside was still wrapped in the original factory plastic and in excellent condition. I snapped a bunch of pics of my unboxing, put on a screen protector I'd ordered (the regular Hori one from Play Asia), put the battery in, charged it, set it up, and I'm ready to go.
Overall, the experience was very positive, and I'm delighted with my new PSP, as is my bank account for not being broken trying to get it (Play-Asia would've been at least $30 more). I'll definitely be ordering some more stuff from them in the future.
