$2100 I have a V1.1 that's been upgraded (not by me) I bought it on this forum about 2 years ago and used it to make my now wife an engagement ring.
That's the only use I put into it.
I don't know the lamp hours right now but it still has lots of life.
I attached some photos of one of the last rings I printed to show the quality left on the bulb is still good.
I also am including about 1/3 of a container of 1:1 cherry
and a little over half a container of emerald.
Almost full recoating PMS (only used for 1 recoat)
-B9 1.1 Upgraded
-1/3 container 1:1 Cherry Resin
-5/8 container Emerald Resin
-90% full Sylgaurd Recoating PMS
