There is, actually, 4ms (grey-grey) with 5ms typical - Viewsonic announced a couple earlier last month. Pricing is unknown, though. OTOH, it seems 12ms is slowly making its way into mainstream for monitors.
My monitor (NEC 1760V) is 16ms, but it's split quite oddly - I believe white-to-black is 4ms, and black-to-white is 12ms (giving 16ms when you add it). Scrolling text that's black-on-white (regular text processing) works out quite well, but scrolling white-on-black has a tiny bit of ghosting when scrolling quickly. Though, having used it for probably close to two years now, I'm so used to it, I don't notice.
About my only regret with my monitor is not buying a big enough monitor. Sure it's a 17", and it replaces my old 17" CRT (so it's larger), but still. I lust for Apple's 30" cinema display... (OTOH, that's getting close to the point of "too big")..
ObOnTopic: OK, I tried to buy a PSP in Canada. Before anyone here complains about the lack of value in the "Value Pack", consider yourself lucky to be able to get that. In Canada, it appears Sony Canada decided to send out a very small number of Value Pack only PSPs. Instead, they decided to bundle the majority of PSPs with a game. Not bad an idea, except the Value Pack by itself is $300 (Canadian), a good deal. The Value Pack Bundle (with game) is $350. Effectively, the bundle costs the same as value pack with a game, except you're forced to accept the game. Great if you like it (Gretzky NHL), but if you don't, you're forced to buy it anyways...
