Hi Paul,
Your kidding... daft thing to say cause obviously your not

that does sound a little steep...
Have a look over here
http://www.openlinksw.com
you can get a single Tier Driver for Progress which will allow you to do just this and I somehow doubt it will cost you anywhere near that price... and I mean anywhere near in a cheaper sense
if you are interested download the driver for evaluation test to ensure it works, then give us a shout for a quote, if you let me know about it, I will see what I can do about getting you a good deal...
HTH
