Looking for a new mouse

Greetings, first of all, let me get through the officially required part;

1. What's your grip style?
Fingertip grip.
2. What's your sensitivity?
High.
3. What's your maximum budget?
No limit.
4. Do you want additional buttons?
Would be good, but I can make exceptions in the worst case scenario.
5. What games do you play?
FPS - Quake Live, Tribes Ascend, Unreal Tournament etc.
6. Do you mind about prediction?
Yes, no prediction for me please.
7. Other relevant information:
Ambidextrous shape - the Razer Diamondback was the best mouse I've ever held in my hands up to date.
Absolutely no acceleration of any kind! 1:1 movement is a must.
High DPI (above 3000)
I don't mind the Z-axis problems as a high sensitivity gamer.
Absolutely NO dynamic DPI scaling!

So, right now I have a Lachesis 5600 dpi which I hate from the depths of my very soul. I used to have a Diamondback which was perfect, but by the time it broke they weren't being sold anymore. So I went for a 1st generation Lachesis 4000 DPI, the ones with jitter (which I didn't mind), it was pinpoint accurate and everything, but the shape was less comfortable than a Diamondback. Sadly, it died and I switched to the Lachesis 5600 DPI which forces Dynamic DPI scaling, which is a piece of ***** and the people who invented it should get shot in the face.

Anyway, I've been looking at the Razer Taipan and Steelseries Sensei, but both have some kind of acceleration, so they're a no-go. Also, from what I've heard the Zowie AM makes you brake your hand and has weird buttons, which is once again, a no.

EDIT: Forgot to mention, I have a DeathAdder, but it makes me want to cut off my hand, I really can't grip it for more than 30 minutes without my wrist hurting.
EDIT2: Preferably a mouse without a thumb or a pinky rest, for some reason I sometimes push them against my pad for increased accuracy.

Any help?

Ah, I forgot to add, I do have a DA, however, I do have a problem gripping it. It actually gives me wrist pain even when using it for "short" amounts of time (like 1 hour or so). However, G400 sounds like something I should check out, thanks! By the way, I just started checking out the Abyssus, except the fact that it doesn't have additional buttons, does it have any other problems?

Thanks again!

Hah, so I'm not the only one with that problem
As for the DPI, it got revamped not that long ago and it actually has a 3.5G version now, 3500 DPI. However, I hope it's not like the Lachesis 3.5G, which has dynamic DPI scaling forced with the firmware. I was hoping it would still jitter, I didn't mind it, nowhere near as much as the dynamic DPI fix, which makes the mouse horribly inaccurate. I hate throwing away money on something they don't write down in the product info:mad:

Hmm, so if it's using an A3888, I assume it doesn't have any kind of acceleration, despite not being a PTE right? Which brings me to the 2nd question, since it's using an optical sensor, aren't they considered inferior to lasers?
