Can't Decide on keyboard please help

[Claymoresama]

Hello everyone. I am trying to decide on which keyboard I should buy to replace my current one. I am not looking for a full-fledged gaming keyboard that sets me back 200 bucks. Mostly I am looking for a keyboard that feels nice when typing. My computer isn't meant for gaming and isn't used for much due to it's lack of a decent gpu. Mostly I would like a keyboard for 30 bucks or less that feels nice to type on for long sessions. I am a college student who uses his computer all the time for everything and I find myself frequently in pain when typing. I even thought I was having carpel tunnel earlier this year, but thank god it was a muscle strain for something else. I have narrowed my search down to two choices, but I am more than willing to change them if someone presents me with a better alternative. I would like to buy from Amazon and not from any other sources thank you.
My first choice is the Sharkoon Skiller: http://www.amazon.com/Sharkoon-Skiller-Gaming-Keyboard-000SKSK/dp/B009K7QB8O/ref=sr_1_20?ie=UTF8&qid=1387850438&sr=8-20&keywords=computer+keyboards

My Second is the Microsoft Natural 4000: http://www.amazon.com/Microsoft-Natural-Ergonomic-Keyboard-4000/dp/B000A6PPOK/ref=sr_1_1?ie=UTF8&qid=1387555331&sr=8-1&keywords=ergonomic+keyboard

These seem like the best for the price though I am not sure how I'll take the ergonomic keyboard. It seems very appealing though I have never had any experience past my friend's Logitech "Wave" keyboard which felt nice, but had a weird learning curve. I will learn the ergonomics if I can get superior comfort, that is my main priority.


Any help would be appreciated and I thank you for taking your time to read this.

If your good at typing then once you go mechanical you'll never go back. Of course mechanical keyboards cost more but they are well worth the price and the cherry mx switches have a lifespan or up to 50 million key strokes. If I we to get a good "non" mechanical keyboard I'd probably look at the Microsoft SideWinder X4
http://www.amazon.com/Microsoft-JQD-00001-SideWinder-X4-Keyboard/dp/B002ZV51DI/ref=sr_1_12?ie=UTF8&qid=1387857896&sr=8-12&keywords=mechanical+keyboard
Or the Logitech Gaming Keyboard G105

I am pretty good at typing I can do about 40wpm or more idk, but can you recommend anything for less than lets say 35 bucks? My budget is kinda tight right now, but a new keyboard is imperative, but thank you for the recommendations that sidewinder looks really awesome.
