It's pointless to continue this since your concept of convenience vs. expense is different than mine. I spent under $20 and have been using the PCIe card with existing gear for about two years and will continue until something goes wrong. Then I will buy a new interface. Why spend that money now when I don't need to?
As another example of this, I have a Line 6 Bass Pod XT Live that is well-past its freshness date but continues to operate properly. Until it fails, I won't be buying a new modeling multi effects unit. It still works! Why replace it?
I drive a 6 year old car. Works great. Why replace it?
I have a Samsung Galaxy 5 phone with a broken charge port/USB connector. So I transfer files via Bluetooth or physical removal of the Micro SD card (plugged into a reader on my PC). Charging? I bought a couple of extra batteries and rotate them around - one is always fully charged, one is on the charger and one is in the phone. A little inconvenient? Yes. But the phone still functions as it should aside from the one broken component and I have found an inexpensive, minimally inconvenient way around it. Will I buy a new phone when this one loses more functionality? Yes. Sadly, there are no new smart phones with removable batteries, so I dread moving "up".
Oh, and the OP literally stated:
He didn't say, "Please answer my question with a suggestion to buy something I'm not asking about."
DigitalMan, I generally agree with your posts but I also notice you are a scrappy fella, so again, I'm done here. If you feel the need to come back again, knock yourself out, but this is a case of two immovable objects and no irresistible force.
