*only* the 4/600 and it's relatively rare memory expansion use 16MB 30-pin
SIMMs and those SIMMS are un-common enough that they're not going for
competitive/MB prices.

If you need lots of memory, get an SS10 - prices are dropping on the base
units and SIMM's, even though non-standard, can be found in the $125-175
range for the 64M flavor.  

I'm kinda surprized no-ones every hacked the Suns to take more memory,
but with ASIC it's pretty easy to build in only the number of bits
you need for MMU's and other "physical address-wide" structures, and
Sun schematics seem hard to come by...

Mods to get an IPX to use 4x32M SIMMS vs. 4x16M would probably be
the easiest, since it has the same 128M w/SBUS capabilities as the
SS2, just depends on whether the "unused" pins on the SIMM sockets
are pre-wired, free, or soldered to ground (this sucks)...

The LX/Classic might be similar, the problem is that none of these
machines are powerful enough to really get excited about and all the
spunkier Suns went with some kind of custom SIMMS/DIMMS...
