The 105 can be a pretty decent brush. I like that you can change them up relatively easily by going with bigger or smaller conversion kits, down to the Super Detail set used in the Xtreme Patriot. I have personally seen some issues with the quality of my more recent acquisitions from the brand, which may make a beginner question their own progress in learning to use the airbrush. But, the company has a good reputation for standing behind the products, should any sort of issues arise.
Others that I generally try to point newbies towards would be the Iwata Eclipse. A true workhorse of a brush that can do it all once the user becomes proficient with it. Built like a tank, they can last a lifetime.
If willing to order from the States (Sprayguner is located in Florida) I highly recommend having a look at the Creos GSI PS289. Fantastic brush at a great price.
I would also suggest at least giving Donna at Maple Airbrush a call - she is extremely knowledgeable, and very helpful.
