There are some promising open source pick&place machines... They've been promising for quite a while now.
The cost in pnp isn't in the moving of a spindle accurately - it's moving a complicated head, from complicated feeder, past (simple, now) cameras, then placing it carefully.
The software is hard, if you want anything usable rather than trivial. Making that, and having it be a help, rather than a hindrance, is hard and takes money, people and effort.
You should be able to search for the thread about open source pnp, where I suggested, quite hard, that what hobbyists need, is a good manual++ system, rather than yet another half-arsed automated pnp machine. (As it turns out, they were building something that promised to be rather less half-arsed. Firepick or something? OpenPnP based software, and an interesting placement mechanism.)
Anyway, this stuff is annoyingly hard. A pick & place machine that gets it right 99% of the time is an abomination. Picking components correctly 100% of the time is hard with a capital H...
I'm sure that, eventually, an open source system will arrive. At that point, you'll discover what a pain it is, to load, program, setup and maintain a machine this complex, especially when it's only used occasionally.
Build or buy a good manual machine, and get on with life... For larger volumes, sub it out. That's the firm opinion of this cynic (who owns more machines than is sane)
Edit: OP has volumes that make a pnp line a reasonable proposition, and he's still struggling to find a good setup. For occasional hobbyist use - I'd stay manual for now!
