If you can afford it then get something nice, something you like the look of may be important.
The other factor which is hard to quantify on paper is the work flow. The steps you weigh the beans, the way the lid opens, pouring it in, putting the cup below the chute. Flicking the on switch, the noise it makes, and then flicking it off. How messy, or not, from the static, how easy it is to clean the insides, how easy it is to replace the parts. The tactile feel of using it.
They have value, and personally, I wouldn't be bother buying something only to spend more time and money to mod it. Get the best you can afford, something you (think) you would enjoy using, and don't regret not getting that something.
My biased subjective opinion, being a Niche owner, is that the DF64 is ugly. It works from an industrial design POV, it will blend into some work top and coffee set up, but I am not a fan of it's looks. The way the dosing up "hangs" on the front. The red LED switch on the side, and then add the wooden lid/bellow feels like an afterthought.
