Derza10 :
I think this is going to be the best one you can get that is remotely close to your budget: http://www.newegg.com/Product/Product.aspx?Item=N82E16823114041&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=
It is $68 though.
I'd be reluctant about getting a Razor Keyboard. There are a lot of bad reviews for reliability on it as well as poor customer service.
Regardless, I had gotten one for my wife for xmas and she used it for about a day and ended up returning it to amazon. The key feeling is quite mushy and didn't really feel any different than a non-mechanical keyboard.
