Isn't DCT Map = Liquidnator? As well, I thought the map tank did not enclose a carto, only ce2 innards?
MAP(Most Angry Pirate) makes two tanks. One He calls the DCT Map Tank and the other is just A Map tank. One uses cartos and the other uses Ce2's. The Liquinator is made by another vendor/maker. The DCT is tight fitting and has flush end caps, while the liquinator is loose fitting with non flush end caps, but does come in a variety of sizes, which is nice.
Here are some links to tanks I own or have owned. There are many more tanks out there, but if I haven't owned it, I'll leave it out. Depth Charge is probably my favorite, but a bit pricey.

Link to a very well priced and well performing tank. Looks similar to a liquinator, but has tighter seal and better price. (Carto)
BDV Lil' Mama 3ml Tank
BDV Big Daddy 5ml Tank
This next carto tank is only 14.00 and it works and looks nearly exactly like a DCT MAP. I have one of these also. Best tank where price is concerned, but only comes in delrin. (Carto)
SmokTank XL Tank
I highly suggest a carto tank over a Ce2 tank.
