To add. It doesn't have to be expensive. I've got the innokin itaste sdna 20 mod. It comes with the t22 tank from amazon for under £30. It's a small 2000 mah built in battery evolv DNA 20 w board mod. It looks awful as it comes with skull inserts on the sides. These are removable (magnetic) and plain ones are included but I've fitted some burr walnut which can also be ordered from Amazon for under a fiver. You can get it in black or silver and it looks class and is a top drawer mtl mod. And being made by innokin you can bet it's built to last and the DNA board is as good as it gets.
