Control chip in ST-7

I think I need to replace the autoguiding control chip in my ST-7. It is a ULN2003L .

Apparently it is discontinued. How does one buy such a thing? My local electronics warehouse does not have them.
(I've called SBIG, and am awaiting return call.....Just want to research other possiblities while waiting.

Any ideas?

this chip is a Darlington Transistor array, nothing complicated. With some research on the web you should be able to find a part with similar specifications. You can start by checking the datasheet at
