Penetration Testing: Mag Stripe reader for POS terminal pentest

[Jason Ostrom <justiceguy () pobox com>]

Can anyone recommend a good value magnetic stripe reader / writer for 
pentesting POS terminals, specifically Micros POS terminals in a retail 
environment?
I'm looking for anyone who has some insight or experience in this area.  
I'm not positive, but I think these are HiCo magnetic stripe cards with 
relevant track data on track 2, but a reader/writer for tracks 1, 2, and 
3 would be great.  This would be used to test for potentially fraudalent 
usage of magnetic cards such as cloning them, fraudalent transactions, 
manipulation of track data and encoding of cards.
Any help or insight very much appreciation!
Thanks,
Jason
