The SP regs you have are nitrox compatible/O2 clean out of the box,
since when does the MK16 come "o2 clean out of the box" ? do you have any reference to back that up?
The MK16 isn't made anymore, but the MK17 for example states it's not compatible with 100% O2

MK17 - SCUBAPRO
The shop was Scuba Sciences in Phoenix, AZ. Service in March 2010.
as the others said... it's a scam.
it's no wonder that Scuba Sciences has gone out of business. (in my opinion).
by the way.... if they didn't do it, then MOST LIKELY they aren't following the MK16 rebuild procedure from Scuba Pro, which states it must use CHRISTOLUBE OXYGEN COMPATIBLE LUBRICANT. P/N 41-047-000 per page 2 of this below document.

Either that or they did it and just want to simply scam you out of more money for a "nitrox use approved" sticker.
at the same time.... I can blame this paranoia on ScubaPro itself....
at this link, ScubaPro says':
1st stage maintenance - SCUBAPRO
Warning: If a Nitrox dedicated SCUBAPRO regulator has been used with standard compressed air it is then compulsory to perform a new maintenance and comply with the cleaning procedure specifically designed for the use of Nitrox mixes and carried out by an Authorized SCUBAPRO technician, before using them again with Nitrox.
The above is true with higher grade mixes (over 40% or 50%), but not with normal EAN32.
