I also bought a new Mac this year and haven't had one issue at all. I bought an Apple Refurbished Model for an insane value with the following specs of 2018 15" MBP with 2.6 i7, 32 RAM, 512 SSD, Vega 20 which retails for $3,549 +tax, and I got mine for $2,717 tax INCLUDED so I saved about $1,000 off the retail price. I personally think the price savings is worth the "risk" since I can easily sell this machine and get all my money back. I would absolutely feel comfortable buying a 2018 model though. There is no guarantee that the 2019 models are a redesign and also there is no guarantee then 2019 models makes all of the fixes people want and there is always something better year after year so that's why I jumped on the 2018 train with the massive savings. Just my 2 cents.
