Yes YES do use the DX, & DO use a cacheing disk controller with 2 or 4 Meg
of disk cache.  Also don't overlook the use of the 486's.  For under 2500
a dealer can get a nice 486 w/ 64K hardware cache that will blow away the
386's.

If you actually have 8 active users you do need all the horsepower you can
get.  The SX is for single users only (IMHO).  If at all possible, get your
supplier to take responsibility for the combination of disk controller/disk/
CPU.  I have had a lot of trouble with combinations that refuse to work.  
There is no good reason, some just don't work.
