Poster, ask yourself, "did i read the OP"?
Because... you kinda didn't.
Even if he types VERY LITTLE, he *absolutely hates* his temporary keyboard. And he cant type on a Tartarus or Orbweaver.
This is kinda funny because the Orbweaver is literally just a symetrical series of keys... exactly like a keyboard. I mean, its got that wrist rest, but - not sure if you know this - you can get thse kinds of wrist rests for keyboards too. The Tartarus is a LITTLE different - they keys are offset slightly and its got the much better right-hand thumbstick/spacebar (the one on the Tartarus still has much more clearly defined directions compared to the one on the Orbweaver), + the scroll wheel, like the design that Razer bought (the Belkin Nostromo n52, which i still have!) and turned into the Tartarus (ts actually almost entirely unchanged from the Nostromo except for they keys being mecha-menbrane).
But i quit using my n52 more than 12 years ago, because i play games where i need to be able to type to communicate with people in chat, and having to take my hand off the controls and move them to a keyboard is a PITA.
Ive contemplated grabbing the Tartarus myself a number of times, and then inevitably remember that having to swap to the keyboard anyway is why i quit using the Nostromo.
If you're worried about a keyboard not being ergo enough, get a TKL or a 60%, then you can let it sit at an angle so you're not pronating your wrist, and it doesnt force your arms out wide to use your mouse.
..../sigh
And, to the OP, i know this is way out of your budget... but check this shizz out:

I sorta want one even though my ROG Claymore is .. 2/3 of that (its got a removable/reversible numpad like that, but no awesome screen).
