Some rigs I own are 7 years old. To amortize the cost of a $1000 rig over 1 year is $2.74 a day.
I've got the glass bug pretty bad and have played the amortization game as well.
Prior to FuckingCombustion I smoked out of dirty, oily, resin-filled spoons that I would just as likely throw away rather than clean after packing them with resin. GAH!
Had my ACL reconstructed and became more familiar with concentrates, but just vape pens and some crumble or shatter on top of burnt bowls (see oily spoon reference above).
Moved up to a Nectar Collector.
Then I decided to buy some glass for home remember thinking to myself "$100, that's the limit".
Started surfing and found some really nice looking glass from some freakaziods going by the name of MotherShip and saw the prices and was like HolyFuckingShit!?!
Got a MS Mini knockoff from DHGate, sold it to a friend. (bought for $50, sold for $50 shipped)
Bought a Double Domer copy via boromarket (American), sold to another friend. (bought for $100, sold for $80).
Another FC member dubbed that one the "Cock-and-Balls".
I was initially confused, but then took a closer look.
Then got the sickness bad and got bit by a piece way of my price range, but couldn't get that thing out of my head; ended up buying it and using it daily for a couple of years (great piece; Locally blown).
Then traded it for a Hex-Nail + extra coils ($700 purchase, ~$500 trade; super great controller).
picked up a travel recycler from the same local blower:
Daily use for a couple of years, then I left it in the car, filled with water, during a hard freeze (got down to ~10*F); shattered the bottom (nearest two bottom bubs in the pic).
I'm still salty about this and it happened ~6 months ago.
I hate being fucking stupid!
I picked it up artist direct (his shopmate actually) for $250, now they're going for $450-$550 (ARGHH!!)
OG blower doesn't think he can fix it, I may have tracked someone down willing to give it a shot.
Got enamored by the crazy six shooter gill perc on this Canadian piece:
Had it for year.
It competed for daily driver status (in for $600 out for $400).
Then this:
and this:
Both from Tony Hernandez direct and hideously expensive (at least for me).
Still have both of them, although one should probably be going.
As a daily dabberI love the functionality and aesthetics of my glass.
TL/DR: It seems that glass holds it's value to a certain extant.
And if you amortize, that will help you justify your purchases.
... AND don't, don't, don't leave water in any travel piece during the winter (or ever, just don't do it!).
...And, where people are sourcing their glass is obviously up to them and there are many variables that influence one's decision, just be safe (I love window shopping on IG).
