Two more candidates:

Yaesu FT-1500  -  Ultra-compact 50-watt 2M monobander with 6-pin miniDIN port.  
Discontinued, but turns up frequently at swap meets. Radio is packaged in a 
cast-aluminum clamshell, barely an inch thick, that doubles as heat sink.   
Unique mounting method:  Instead of the usual trunion mobile-mount bracket, two 
#8 bolts extend through the clamshell from top to bottom. Makes it really easy 
to mount the radio to the inside wall of an ammo box with no wasted space, for 
portable ammo-box trackers and digipeaters.    This is an excellent platform 
for all kinds of APRS applications. Grab any and all you see at swapmeets and 
ham fests!

Yaesu FT-8900  -   FM quadbander for 10, 6, 2 and 70cm.  Has dual receivers 
capable of cross-band digipeat between any of these bands. I've actually used 
it, in my car, to digipeat 144.39 to UHF for radio club demos at meetings deep 
inside buildings.  It has the 6-pin mini-DIN port with the cleanest discr 
output I've seen in a ham (not commercial land mobile) rig. The accuracy of the 
300-3000 Hz de-emphasis curve on the "1200-baud" pin of the miniDIN is also 
among the best I've seen ever.     Note that the TYT-9800 (Chinese 
identical-looking knockoff of this radio for $100 less) lacks the all-important 
data port!
