I'm just wondering if there's a Sky atlas that plots stars up to 10 or even 12th magnitude and where I can get it? It's gonna cost a BOMB isn't it??

I know there might be posts that are gonna ask why I need so much detail or so many stars, well, let's just say I'm greedy!!
HAHA ... No, actually, I wanna do a little survey and study on different skies and sky conditions and need a more detailed chart than what I already have with a 6.5mag Bright Star Atlas and tiny(physical size) 8.5mag(I can't remember exactly, can someone confirm) Peterson Field Guide to the Stars and Planets.

On that note, I read somewhere that SkyAtlas 2000 covers stars to 8.5 mag. Can I confirm that with users here? Anyone knows where is the best/cheapest place to get it in Singapore? (Open to shipping it in if cost+shipping is considerably less than local)
Thanks for looking!
