JDR (800-538-5001) has got four-port cards priced at $89, $139, and $199. Price depends on the type of UART provided and software drivers. It doesn't say explicitly in the catalog, but reading between the lines leads me to believe the $199 card can multiplex all four ports on to one IRQ, and the less expensive ones can't. -- John W.
