I wouldn't advice you if you wouldn't like to see your American / European games being censured or changed. That's why I've bought myself an European PS3 "as well". Sony Europe will be pleased with me since "ages". I'm a lot less lot pleased and yes I'm keeping my JP PS3 as well, so 2. Cheaper, 40GB version of course, plus 30 Euro discount, I'm crazy, but not that crazy *cough*. Lets hope it will be a great investment for the upcoming 10+ years.
Still if you're planning to buy a JP PS3, just contact me and I'll give you the address from the shop where I've bought it. It cost around 400 Euro including shipping to order there. I didn't have to pay taxes, so if you're lucky, neither do you 
And you're not able to play those PS2 / PS games anyway, as the 40GB doesn't have BC and there's no White 60GB version, or else I would have that one too, instead of the black one
