You should probably think about getting the 486/25, since the price
point of that machine (from most manufacturers) is almost exactly the
same as a 386/33 + 387 and you'll get something like 25% better CPU
performance and 50% better FPU performance. I bought a 386/33 in
January and now regret not having gotten the 486/25 instead. Sigh.

Unless you think you're going to do mongo amounts of expansion into
high-speed peripherals or networking, an ISA (which is a way of saying
"IBM-AT expansion bus" without using Big Blue's trademarks {grin}) will
do. EISA still seems to command a $500+ price premium, although this
may drop in the future. What is very important if you're thinking of
moving toward the UNIX or OS/2 environment is to make sure that the disk
subsystem you get is as fast as you can possibly afford, as this makes a
*BIGGER* difference in the throughput you'll observe.
