Not being super computor literate re: technical terms, I got their web site up and then called and spoke to a PERSON that walked me through each and every item available, what the function was, and his recommendation. Best thing I could have done. Received all my stuff in a short time,(Dell 8200 computer with tons of memory and speed) great scanner (Scanjet 4400C), (Epson 880 Series
Printer) and standard speakers that can still shake up the roof when I play a Sousa march!!!!DELL is the way!
