are there any other alternatives, aside from the poker 2 and the pure?
Yes, the first Poker and the Pure Pro (I wouldn't recommend either). Ducky is also going to sell a 60% board soon. Another alternative would be a GH60, you can take over some unpaid orders in the group buy thread, however you then need to buy switches, a case and a cable too.
from what i've read from the GH wiki, the pure beats the poker with regards to form factor, im wondering whether the problem persists with the poker 2?
The first Poker is prone to PCB bending because it has no plate and is not connected to the case in the center of the PCB (the Pure is, but has no plate as well). The Poker 2 however is plate mounted which resolves the problem.
also, how do the function key layouts look? i can't find the layouts anywhere, and all i know is that the arrow keys are on wasd for the poker, and okl; on the pure... is that true? i also heard that shift/win/alt/control act as arrow keys, and i'm a little confused.
The Pure has RWin, RAlt, RShift and RCtrl as arrow keys when pressing fn+space (it's a lock mode). Whilst pressing fn, you can also use OKL; as arrow keys. Heres the function layer of the Pure:

On the first Poker, the function layer looks like this:

The Poker 1 and 2 do not need a Tsangan kit, the Pure does, the Pure Pro is not even compatible with a Tsangan kit.
tl;dr: The Poker 2 is pretty much the way to go, unless you
need that extra key on the Pure, also avoid the Pure Pro.
