Financing Computers for Business?

Mercutio asks: "OK, I've been handed the responsibility of acting like a grown-up and changing from my normal day-to-day IT job to actually making decisions involving someone else's money. Specifically, I've been asked to deal with all the variables associated with purchasing/leasing computer equipment (desktops, laptops, printers etc) and I'm feeling a bit out of my league. Anyone have any tips for dealing with leasing or financing equipment, companies to avoid working with, or mistakes made in past leasing/purchasing arrangements? Any company that was really great to work with? Any help is of course appreciated. Thanks."

Good Question...

Concrete, I are requested processing all variables and the purchasing/leasing computer equipment (tabletop, on knee computer, printer association and so on) and I feels the position outside mine union. Any person has all definitely skillfully for the processing lie or the financial equipment, the company avoids working at, or wrongly violates through the leasing/purchasing arrangement?
