[X4U] 35mm Slide Scanner for OS X iMac

[Paul Biddlecomb]

My mom has thousands of old 35mm slides that she wants to scan in to  
her iMac (iLamp, 700 MHz, OS X 10.3.x (soon to be upgraded to  
10.4.11))  She currently has an HP All-In-One (printer/scanner/copier/ 
fax), about 4 yrs. old, which she has used for scanning photos into  
iPhoto.  Does anyone know of an inexpensive slide scanner, or an  
adapter that would work on her HP AIO?  Preferably under $200?

Many thanks,
Paul
