[CQ-Contest] What rig to choose for a one-time fieldday MM setup?

[PA5MW, Mark]

Looking for the ideal HF rig for a one-time 6 band  field-day MM setup.
Run+mult stations, so about 12 HF rigs in total.
All 160-10m stations using the same rig. All with external filtering. 
All with additional PA.

Requirements:

1) Simple to use interface
No learning curve, anyone can learn operating this rig at contest level 
within an hour.
Any required fine adjustments, make that *problems*,  in the field for 
the whole MM setup needs to be easy.

2) No quirks.
No unsolvable issues like leading spike at PTT.  No horrible high phase 
noise.

3) Small & lightweighted, can withstand some rough handling during travel
Must fit in suitcase.

3) Price level must be very low.
Any additional tips for buying and selling the rigs after the FD contest?


Your answer, based on you own or club experience (no 
textbook/performance lists wars) will be much appreciated !
