As far as I can tell with my 'enhanced 512' compared to my friends' mac+'s
the differences are:
	less memory
	no SCSI port

I have made no exhaustive comparison, but old things which bomb on his
mac+ also bomb the same way on my 'enhanced' 512. Things which run on
his but bomb on mine are all things which run out of memory. We have the
same system/finder combination.

If the 'enhancing' plus the RAM expansion costs more than the Mac+, I'd
go for the Mac+. Reasons:

	Replacement SIMM RAM's are becoming available that make the expansion 
	of the Mac+ to 4Meg simple, and eventually cheaper, than any add on 
	board expansion to 4Meg for the 512 Mac.  

	The number and type of SCSI peripherals which are becoming 
	available, useful, and multi-vended is expanding. Because of the
	multiple sources, they are also relatively inexpensive.

In respect to your wish to avoid 'growing pains' relative to your 
existing software base, I'm afraid it makes no difference. Many of my
older public domain programs do not work properly, or at all, on the 
new system/finder with HFS. But note: keep them on disks with the old
system. They still work there, just no HFS, scrolling menus (unless
you use the public domain scrolling menu installer), grow box. You can 
even use the latest finder (as far as I can tell.
