  All too true, but sometimes the comparisions is a little unfair. I find
when I look through a databook I usually drift to the newest/greatest/
fastest part that was just brought out yesterday. The HC parts have 
been out for quite a while and and the run of the mill stuff is cheap
and not hard to get.

   68HC11A2 was less than $20 dollars from Active. They now have $25 dollar
minimum on that part so you have to buy 2 but that's not bad for the
hobbiest. I think it is well worth the extra expense over the
68705P5 or R3 which can be had for about $8 or $12 respectively. The
poster mentioned the 1468... CMOS series which I find harder to 
to find than a 68HC11A2.

   The 68HC11 F series is hard to get of course, but it was only introduced
this year.
