Interesting discussion, and I agree with Ian on glass bottles. 

I don't think vendors will change their kits, modify or buy better softer
plastic squeeze bottles is more likely.  BUT I think they would do us 
huge favor by staing the volume (size) of drop for theirparticular bottle
for those who have fingerjoint/other painful problems.  This gives us 
an ALTERNATIVE to not use squeeze technic.  I am not sure which vendors
provide this information OTHER than VECTOR in their new NovaRed substrate
kit, but it was greatly appreciated, immediately utilized.  I could determine
all this myself, but it should be part of their kit quality assuarance and
provided upon purchase to everyone.  No all bottles dispense the same
size drop (different mfg sources of bottles), and vendors should know what
their bottles deliver.  

Hopefully vendors are listening carefully and for those who already do it,
I commend you for helping us out.
