Anyone have any experience with USB to RS-485 adapters?

I've stumbled across two on ebay. One seller has 100% feedback, the other 98.5% positive.

I'm tempted to buy one, to avoid the hassles of USB to RS-232 then a 232/485 converter.

Any one ever tried anything like these, maybe some other source?

1) USB 1.1/2.0 to RS485 / RS422 Data Signal converter
appears to be a larger unit, no visible USB port, probably cable connection on hidden side.
$54 USD plus $15 shipping from Shanghai, China
USB to terminal block

2) USB 1.1 to DB9 connector
Similar to USB-RS-232 adapters, USB cable with adapter housing a DB-9 connector
$39 plus $19 shipping from Hong Kong
