it probably is this... minus the mask they are offering.
the tank may be hard to get off as it is full, and its easier to remove them whist dry firing the marker (as the emek does not come with an on / off asa as standard)
My 2p from buying an EMEK this year -- it is well worth the cost of a brand new one, but if you can get one for less than retail, you are all-ready quids in as the marker itself is so good!
The bottle will need re-testing every 5 years, and if it "needs a new reg" that could mean that it is not hugely worth considering in the price of the package... but I really wouldn't be turned off by this.
for 180, I would grab it, buy the pops asa from somewhere ->
