Thanks Ted, and others, for your responses.  And, yes, I agree that 
Crucial does look like a good source -- for you blokes in the US.  
Unfortunately, it's not so great for we Aussies because it ships stuff 
by DHL, which has two downsides compared with normal airmail:
1. It's relatively expensive (USD20) and
2. It *automatically* attracts Australian 10% GST on all imports 
whereas mail usually doesn't for minor value (i.e. <AUD500) stuff.

Which means those 256MB DIMMs at USD70 from Crucial suddenly become 
USD99 each (or about AUD136 at current rates).  

Hmm... but maybe not so bad in lots of two (about AUD240 in total by 
my estimate -- assuming that $20 freight charge will cover two DIMM 
modules and there are no other import "gotchas".  (But there probably 
are!)

Incidentally Ted, why do you say CL-2 DIMMs?  The memory specs from 
Dell for the Dimension 4100 series say:

Architecture non-ECC PC133 SDRAM 
Memory sockets two; gold contacts 
Memory capacities 64, 128, and 256 MB (non-ECC) 
Minimum memory 64 MB (non-ECC) 
Maximum memory 512 MB (non-ECC) 
Frequency 133 MHz 
Clock cycle 7.5 ns (supports 4 clocks only) 
CAS latency 3 
SPD revision 1.2 A 
Buffering unbuffered 
Voltage 3.3 V 
Data bus width 64 bits
