What I really like about it is that it has heft in your hand. I dislike working with drawing implements that are light weight. It comes with HB leads, so here is where you might have to spend some money - but really you're spending money to save lots of money in the long run.
Go to an art supply store and buy 2mm leads - 2H, you already have the HBs, 2B, 4B and 6B. Keep a Derwent 9B on hand and you're set for literally years of drawing!! I bought enough to have one lead holder for every weight of lead I use!
I like to draw with a hypodermically sharp lead - and these are the way to do that. You get what we used to call a leader, that's a rotary sharpener for 2mm leads. I just really love it when things work out - you know?
