C cross development tools for HD64180/Z80/etc.

[Mark Bartelt]

I'll soon be writing some code for a new medical instrument, containing
an embedded HD647180X processor (Hitachi's enhanced version of their own
HD64180 products, which in turn run essentially the Z80 instruction set,
from what I've heard).  I'll need a good C cross-development system that
runs under MS-DOS.  Hitachi's product sheet lists three vendors who have
one available:
		American Automation
		Microtech Research
		Decmation/Z-World

Does anyone who has experience with some or all of these have anything
to say (good, bad, whatever) about them?  There's quite a cost spread
between the least and most expensive.  (Z-World, curiously, offers both
the cheapest (their old product) and the costliest (their new one, which
does indeed look quite spiffy).)  Are there any others, not listed on the
Hitachi product sheet, that I should be aware of?

Thanks in advance for any recommendations.
