5 1/4 Floppies

Hi, I need to digitize or at least assess the data of 373 5 1/4 floppies in our collection. I have a couple leads on how to do this. One is to buy a used drive and a USB conversion kit, which would probably end up being around $200. The other are digitizing services, the only ones of which I've found are at least $20 per disk.

I was wondering if the community here knew of any alternatives, or had some tips on this endeavor.
