I have a product that uses an RS232 connection hardwired but it has potential to be used with a serial to internet interface as well.

I have no experience with any of these converters -- some of the ones I have bookmarked are siteplayer, netburner. Also one on Ebay "usconverters". ?

I want something that the user can set up with a MINIMUM of hassle.

Also, something that is complete, not the module concept that needs a PS, case etc.

Any recommendations?

Thanks.
