An analog T1 line for us is about $250 US and can get us 23 voice > lines.

By definition a T1 line is digital. Apparently you're being quoted with a box to convert the end point to 23 POTS lines/circuits.
Each circuit on a T1 has 64KB of data bandwidth. How much it's costs to get it as data vs POTS varies by state, vendor, "deal of the week", etc...
