Thanks guys.

Soldering skills = 3 (1 - 10 scale)
Credit Card skills = 4

So the credit card wins again !! I am going for the Schimar !!

Another option is to build your own buffer circuit from a couple of
MAX232 IC's on some veroboard. I did this in the past as I suffered a
similar problem.

Might be your cheapest option by far if you are handy with a soldering
iron.
