Don't go too cheap!  I recommand that you go with a managed switch 
anyway.  You'll be able to debug network related problem starting from 
level 1 of ISO 7 layers reference model!  With a managed switch, you'll 
be able to see errors generated by faulty nic / cable / duplex mismatch, 
etc. and have flexibility for the future.
