I'm sure that this will get marked as "liability issue", "not authorized to repair", or "support your local dive shop":
I recently put together a nice dive package for myself with new regs, bc, wrist computer, accessories, etc. and a console consisting of a 12 year old Sherwood SPG, The Source, and a compass which I had to throw away (no more used eBay crap for me....) Everything works fine, but recently had bubbles on this guage (corrosion in my HP spool) exactly like this article:

I took it apart, carefully cleaned, matched new o-rings, assembled, tested, and the leaks vanished! Yea! I'm very proud of myself, and now I know more about my own equipment.
But I can see how the $3 HP spool could desinigrate and ruin a dive. So, "I'd like to purchase a spare spool to add to my kit." The canned dive shop response is: "That part can only be sold to a certified repair technician."
So, I sit here grumbling about the fact that I can replace o-rings all day, but not this part. I havn't asked any other dive shop. I know that it's an easy repair (I did it!) and my local shop could do it for me (support your LDS), but I just wanted to have a spare spool just in case--in case they don't make this part anymore. (grumble, gripe, moan.) Fine, I'll just buy a new guage, and dump this one back on eBay!
What do you guys think?
