Sounds like a good idea, bit like these

I am not familiar with them first hand but they were certainly on the cards when we were looking at machines, so I did look at them quite closely but only had a full in person demo of a MY100. I'm guessing you are looking at perhaps an MY9 and the feeder arrangement you are liking is 'Agilis' system? There are lots and lots of people out there with MyData's so there is probably one near you to have a look at if you ask someone nicely. ~2 years ago I could get an older TP11 series with a healthy complement of TM feeders for a little over £22k, so they are way more expensive than an RV.
IMHO
Pro's :
Agilis gives you great, low changeover times (which you don't need)
Built in Vacuum Pump so no need for noisy compressor and dryer
Lots of them out there ( I can see 22 listed for sale right now)
You can swap feeders on and off during a job if you need more than you can fit on your machine at a time
They seem to retain value better than many other brands
Easy to get more feeders (especially the pre Agilis 'TM' ones)
You can update a TP machine to take Agilis feeders (but it's £££)
Genuine MyData expertise available outside of MyData
Cons:
Agilis wastes parts because it uncovers more than one pocket (this is only bad if you do lots of changeovers and value those parts)
If you need a lot of feeders loaded at once you need a big model as all feeders are on one side.
Without a HYDRA head they are quite slow as the head has a long way up and down the machine to travel
Split axis - more to go grong?
Official support is expensive
Official support on 'TP' series is only available at a base level SLA
Agilis 'elements' are really quite expensive considering they are a piece of machined metal with a chip and some contacts.
Lots of different vision system options to choose between
There are mechanical centering ones out there which it is probably wise to avoid
Its not a shiny point and click windows world from start to finish.
From the type of work you describe you won't spend much time setting up and perhaps most of your setup time will be spend defining new IC packages, it also sounds like a job for the smallest machine you can find

Plenty of us sub contractors are quite happy to do 100 PCB's, 4 panels of 25 small pcbs, or even one PCB. It doesn;t sound like complex or time consuming work I would certainly recommend getting a goodly number of quotes before spending a fortune. Those that want the work will probably quote similar numbers, the sums after all are all the same.
