The PR lineup of machines is that of entry level business, high end consumer. So keep that in mind. That brings about advantages and disadvantages.
I will say this, that lineup of machines (versus the totally commercial lineup of not just Brother machines, but all of them) is perhaps the more accessible to lay people that have zero experience otherwise (at least in my experience with teaching others). That comes with it some cons as well if going down the embroidery rabbit hole. PR machines have very specific quirks that will take time to compensate for, not necessarily wrong/bad, but they are different and really only those machines have them. Not to say that the total commercial machines are all that hard, sometimes that industrial aesthetic can have a little bit more learning curve. It all depends. However, going with the more industrial machine and learning off that first, be able to handle just about anything that comes one's way after that (Brother commercial machines are also very, very good, although I do prefer Barudan's, stick with the well known ones in general should do right by you).
If going with the PR machine, I would suggest their software. Things like applique stop codes etc don't really come out using something like Wilcom (which is better compared to Brother software in general, but not when dealing with these machines specifically, once can work around it with something like Wilcom, but it will require more effort and more than likely not getting much support at least officially).
I would suggest the 10 needle and not the 6 needle, but I realize that for budget reasons, this may not happen. Colors and doing changes for designs that have more than what the machine has already, is actually more tedious with Brother machines (going back to specific quirks), so the more than can be handled from the outset, the better you are. Unless you just want to limit the design number to 6, but that would be an artificial limit.
I can't help much with a good retailer within your area.
