In the market for a 4 or 6-head machine

We currently outsource our embroidery and we're looking to bring it in-house. When I first began researching machines, I was finding that I could purchase a brand new machine for around $25,000 for a 4-head, $30,000 for a 6-head.
This would be new, delivered, installed with training. Since it would be our first, I figured that this would be the best way to go (brands like CamFive, Highland, Ricoma)
As I continue my research, I'm finding that the top brands are Barudan, Tajima, SWF. I'm also finding that these machines are double the prices above.
I realize that these machines are better built & have a better reputation, but would it be a mistake to buy the lesser price machine?
Are the more expensive brands the Mercedes of embroidery, but the others will do a fine job??? I've read some horror stories on the less expensive machines.
If I buy a used Barudan, Tajima or SWF, how would I get training & service (I'm in the suburbs of Chicago).
I'm not sure that we can afford to spend $45-$50,000 on the high-end machines.
Any advice on which brands to stay away from & which to consider would be appreciated.

Please do not get a Ricoma. They are poorly built and stitch terrible. I run Barudan and my business neighbor that outsources to me got a Ricoma so he can do his own embroidery. I still do his embroidery lol. Can't even complete a job.
