Need cheap, small inkjet

[kranky]

I'm looking for a very small, cheap inkjet. Doesn't have to run on batteries but OK if it does. I need to take it to a show and do a little onsite printing through a Win95 laptop.

Need "small" because I won't have a lot of room for transporting nor storing it at the show. My HP 612C, although small for an inkjet, is much too large for the job.
Need "cheap" because I won't have a lot of use for it afterwards.

Any ideas are appreciated!
