What size drawers and how many do you want?
I am in the same situation, looking to replace some drawers under the workbench with full extension deeper drawers.
I do want at least 24" deep inside drawers, about qty 18 5" tall, some 13" tall and some 3" tall. The box to hold the drawers would be about 32" tall, 30" deep and 8' long. I figured about 7-8 sheets prefinished plywood, $85 a sheet, and about 26 full extension slides, about $20 a pair. About $1200 in material and alot of labor to make.
BUT, I will have the size drawers I want when I am done.
Here's a couple links to check out to buy some:

Poke around the site, they also have alot of choices for cabinets.
No luck in finding used Lista around here at a good price. One used in rough shape Lista 4-5 drawer cabinet is around $500. Still looking...
