I have been buying these little guys for years and I get a little pissed everytime I do since I have not had the time (or patience) to rig up an adapter that could do what this does. I have 4 projects (including our new showroom) I need them on coming up shortly and am getting the order ready (about 20) and I was wondering... Has anyone has come up with a more cost effective alternative to the CM232 module?

Maybe a combination of other parts/adapters?
Maybe a similar unit by some other manufacture?

They do the job, I'll give em that, but man what a price tag on that little guy.
