I've fought quite a bit over what keyboard to use as a replacement for my Logitech G15 (v1). The biggest problem that I have is that most keyboards don't have a windows key disable feature, which I do use on my G15. Even though I'm pretty sure I've seen software solutions for it, I'd rather just have a physical switch.
I ended up ordering one of those Corsair K90s after reading the review on Anandtech. Unfortunately, the top two tech e-tailers (Newegg, Amazon) don't have them in stock right now, so I'll have to wait a little bit. I was considering dropping the macro keys, but after playing Magicka, I think I'll keep them around.

I also like the fact that it doesn't have the L-shaped enter key, which is oddly common on some high-end keyboards (I'm looking at you, Steelseries!).
I don't mind spending the money on a keyboard with good features. I used my G15 for a ridiculous number of years, and the only negative is that I ended up ripping one of the G keys off. I would adjust the keyboard's physical position by tugging on that key with my pinky.
MX1000 is a not a gaming mouse nor was it good for gaming. G700 blows it away in every way. From better scrollwheel to adjustable dpi on the fly to higher dpi, can be set to not to go to sleep, higher polling rate, more buttons, lighter and chargeable while you're playing. I have both. My current MX Revolution(use for non-gaming) is better than the MX1000. The MX1000 also had issues on certain surfaces, not with the G700 or MX Revolution.
Currently, I use a G700 mouse and G13 keypad for gaming.
I use a G700 mouse as well, and it works fairly well. To the person that was buying one, I would say my only (minor) complaint is that I wish the cable for the mouse was a little bit thinner like my old G5's braided cable. Although, I also wish Logitech had a G700 variant that was only corded since I've never used mine as a cordless mouse.
