Martin,

here are some replies. I don't think I know everything there is to know and the 
waters are pretty murky. But there goes:

I don't know that answer for sure - and I doubt anyone does without having 
both instruments. Remember that we are distinguishing between accuracy 
and convenience. A strip reading device is more expensive because of 
convenience features, but not necessarily more accurate than a 
single-reading meter.

You may want to price what this would cost you to do by sending out to a good 
source willing to make you custom profiles.

Scanner-based profiling is something I haven't done. From comments here 
and from just theory in my head, it's a no-brainer to buy the Swatchbook or 
equivalent single-read spectrophotometer (that would double as a 
densitometer and dot gain calculator).  In this case the $500 would represent 
a huge step (as opposed to other "steps" you outlined for higher end 
products).

The only one I no longer need is a portable reflection densitometer  X-Rite 
404. As new condition, 12 years old, in its case with power supply. Useful for 
measuring across large prints and not dragging a wire behind you (it's 
rechargable). Price to be determined.
For an alternative source I would look on eBay. Last time there, I bought an 
810TR (refl/trans) for $750. Costs new $3500!!
