The goal for me is to have feeders that are both very easy to fill and exchange, and that can also be put in random order into the machine, and the machine knows where the feeders are and what part each of them contains.
I'm thinking about using an N20 motor inside the feeder for reliability, and cutting the cover tape lengthwise with a knife and fold both flaps outward (several commercial systems use this).
Also, with those chinese machines, you just get a magical box. If that box does what you want, then go for it. But if you want something else, then it gets difficult very quickly.
I have never ever seen a PnP machine that's optimized for prototypes in the way I've described. If anyone has got a link, please post...
You make fair points. Each of us are looking at different combinations for what works best for us. I do allot of individual rapid prototypes, but I also do this for a living so my setup will be allot different than a hobby person just doing a couple of designs a year. For that person, the NeoDen YY1 makes some sense. It is basically taking over the older Charmhigh 36/48 systems. Its feeder design also looks like it does well with individual strips.
The main issue with all of these machines, however, is that the amount of time it takes to load the machine is generally > than the time to just do 1 board by hand. To your point, no one has solved this problem, but a cheap/compact feeder would be a critical piece to solving it.
In Stephen's case, from a business perspective he's stuck because on the one hand he's competing with the $3K PNP market which he has little chance in penetrating because its established, and the DIY build it yourself market. Paying $1745 (LumenPNP V3) plus shipping/taxes, and your basically back to the same price as the other players which are more functional. I dont doubt he will sell some machines. I just dont see any real business problem he has solved.

I cant speak for the other chinese machines, but I know the Charmhigh and QeHi machines pretty well. All PNP machines (even the $1M) have their quirks you have to work around. Once the machine is running and stable, though, they all pretty much get the job done.
As far as "want something else"... That is what the IC trays are for.
Nothing stops someone from buying one of these low cost machines and putting OpenPNP on them, but it would just be a step backwards. Their just a mainboard with stepper amplifiers. The QeHi machines are ideal for this because their about as simple of a design as it gets. You could convert them in a day, but the reality is that there is no real reason to do this. The chinese software is actually pretty damn good, and gets the job done.
My larger point and I see this with people complaining about the LPKF prototyping systems is that nothing about designing, making, or populating pc boards is "point and click" out of the box. A person has to fully understand how each of these systems operate as well as learn their individual limitations/quirks/work arounds. Its not rocket science to do this, however. I make and populate custom 4 layer boards daily, and can do it in a couple hours. Its not some very expensive equipment I use either. Its just allot of hard, methodical, and persistent work.
