Although the 386-40 gives you good value for the processing power/price ratio 
compared to the 486SX-25, you will still want to consider the upgradability 
aspect of the system. It is good if you can get a 486 motherboard that 
can support up to the 486-50 CPU.  By changing the oscillator and the 
CPU for the 486SX-25 system, you can upgrade it to a 486-50.

Although the price of the 486DX50 chip is rather high at the moment,  
I believe this will drop quite significantly when AMD comes out with their 
486 chip next year.
