Digital BW, The Print

I would like to scan some of my best negs, ( BxW and Color ) and
enlarge them to at least 13 x 19 or thereabouts, a majority of them
are 35 mm , it would be nice to scan 120 but I am only working with a
$500.00 budget.

Do I need to spend more ?

What would you recommend ?

I am printing with a 2400.

Thanks Mick.
