I wouldn't bother selecting a BC based on serviceability. Unlike a regulator, there's not much to go wrong. And if you're that far afield, you should take parts with you. A replacement dump valve for mine is $3.95, and a replacement power inflator is $16.95. Neither of those are just going to fail out of the blue, but if you're really worried about it it's a minor cost and small size to bring the parts. The service tech may not have seen a BP/W before, but the fact is the mechanics of it are exactly the same as any other BC. Just because the physical appearance is different doesn't mean it actually is a problem to service.
LOL - what makes you think there is these mythical service techs everywhere? Without even travelling - the Zeagle technician for my state loves them but does not recommend them because of the difficulty and time in getting parts. There are some places where there is no such thing as a service tech! Nearest service technician when I needed inflator hose replaced was in South Africa or Mauritius for any scuba gear of any brand from what you refer to as poodle jackets to hogarthian rigs - the dive shops that do service gear go on holiday during cyclone season. I dived in hire gear. I did say whatever suits the OP and her intended dive path - just my opinion and just trying to encourage a person buying their first set of gear to buy what they feel comfortable with.
The mechanics may be the same...the understanding of concepts may not. If OP goes BPW good on her - if not, good on her too.
