I will gladly help you out. Both the Taz 6 and the Mini are great printers, one of my clients has a Taz and it has proven very dependable.

If you want a Mini however, Check out the Mini 2 first. It's on pre-order right now, it comes out in 5 days(Jan 20). Lulz really went all in on this one. It features several major improvements like - 20% more build(still less than the Taz though), a belt driven z-axis, and some seriously quite stepper motors.

But you really want to ask yourself what you need in a printer. Dependability is important to us all, but it's VERY important in a commercial environment. If my home printer goes down, its a PITA but it is not a major deal. However, if my prototyping printer goes down at the wrong time. I could miss an important deadline, and that could easily cost me a valuable relationship depending on circumstances. If a client is depending on me to deliver on time and I don't, they will probably not use me in the future(and that could cost me many times the cost of any 3d Printer) Bottom line with Lulz, they are more expensive than other comparable printers BUT that difference in price allows for high quality parts; tight quality control, plenty of R&D, and consequently, reliability even in a commercial environment. If that's what you need or want, Lulz is a great option. If you are trying to spend less money and what me to provide insights on cheaper printers just let me know :)

About the printer I used to make this: For this print, I used PLA and my fastest printer, hence the excessive z banding noticed in the pictures. Which, just so happens to be one of the cheapest i3 clones you can find and the first printer I bought. I must mention, If I were to factor in my time it is not so cheap. I spent a few hundred on printer+upgrades, but I spent a couple thousand dollars worth of time getting it to this point. For me it was worth it because I wanted to know everything about how 3d Printers work and this option required me to do a lot of research (I can't recommend this option unless I know someone well. It is defiantly not for everyone).

As far as the blog you linked: I read through most of it and it seems to be a proper and accurate article. If you use that site often and want tohelp out the people that write the articles you read, use their link. They will earn a small commission and that helps people like us afford to spend more time on things like this. That really comes down to what people and businesses you want to support. Conversely, If you use one of the links I posted in the start of this reply, I would get a small commission. Do not feel any obligation to me, I love doing this regardless. I've worked hard over the years and I am comfortable. In my case, I have a deep passion for engineering and have been in the prototyping industry for a few years. However, I have spent most of my time making things that other people wanted and its gotten a little boring. So, a few weeks ago I decided to start building more of the things I want to make and sharing them on the web. I couldn't be happier about it! 3D printing feels brand new again, and I find myself in the lab happily pulling 12+ hour days. All in all I hope I was able to provide you with the answers you are looking for, feel free to ask me any question, any time, cheers :)
