If u're not in a hurry to buy now, maybe u can hold on a little longer to see if the upcoming starcraft II keyboard will suit u..

since starcraft II beta already started, i think this keyboard will come pretty soon..
and btw i think Razer is due for a new keyboard.. havent seen any new keyboard from them for quite a while already..

I don't think you can get tarantula at this hour as they have stop production
You can still try though. I have tried the belkin pad it is crap. Go for G13! Much better interms of quality
For keyboard, you can go for 7G steelseries then use G13
I am using Tarantula+G13 combo  So far there is no sign of keyboards coming out from razer
I still like macros on my G13 compared to my tarantula
So if you are in need. BUY BUY BUY. If you can wait which can be 3 hours,3 weeks,3months or 3 years.
