With the BAT preamp having a phono stage and a tape output, you've got exactly what you need to provide an RIAA-equalized line-level signal to an a/d converter, or to a recorder that contains an a/d recorder. There are lots of choices, ranging from a little more than a hundred dollars on up into the multi-thousand dollar range.
For really good quality, I would still recommend the Sound Devices 702, but there are lots of much less expensive choices you can peruse at B&H's site here.
I've used a Marantz PMD670 ($630) with very good results, using its line-level inputs (its mic amplifiers leave something to be desired). Like the Sound Devices 702, it records to compact flash cards, from which the digitized files can be subsequently transferred to a computer. The Marantz unit has a usb interface, while the Sound Devices uses firewire. Or alternatively, the Compact Flash card can be removed and inserted into an inexpensive card reader which connects to the computer, typically via usb.
