Is there a cheap daq kit for matlab?

Is there a cheaper version of nidaq out there. Best if it's like usb. That can read and send digital signal up to 1~5Vs. Up to 5 Digital I/O is enough and best if it's below 70 bucks S=.

Thanks!

Keith, how about Digilent's Analog Discovery? It is really affordable from what I hear, especially for students.

Just the 99 pack is good? It did say Digital I/O as one of the features. Can you give me a simple piece of code that works for the kit?

if detect digital input (sensor)
    send digital output port 1(turn on led) 
    pause(2)
    send digital output port 1( turn off led)
    send digital output port 2 (1 to 5 volts I choose)

Can the analog discovery do the last line? I am not sure if so can you show it to me before I make a 100usd decision. Thanks!
