Back in the mid 80's I remember using the Tek 7D20 digitizer plug-in. It only had a 20MHz sampling rate with an over sampling bandwidth of 70MHz. It was OK for sampling in the audio range but not go at TTL rates.

I've looked into the Tek 2230 before and found it's performance and ease of use is nowhere near the Fluke PM3390. It's also very hard to get detailed info of 2230. For Fluke PM3390, you can purchase a service manual for very little but some parts are very hard to get. Then you end up getting a few units and start cannibalise them.
