Digital BW, The Print

I have two questions about how to get my old B&W negs ready to print 
digitally:
1.  A camera shop guy says I can't make contact sheets on an inexpensive 
scanner because they only have one light source and all I'll get is the center 
third of the negative strips. Anyone out there scanning neg strips for contact 
sheets?

2. The same camera shop guy said the Nikon V scanner isn't acceptable for 
B&W because of the light source. He says I have to have the Minolta 5400, 
which is $300 more, of course. Is he right? I want to scan B&W negative film 
and some color slides. I want to make 13 X 19 prints.

Cheers,
