That’s ok , I recommend you purchase it via Amazon , test it out for your need, get some tips here if you get lost and keep it if it is what you are looking for or return it back if it do not worked for you. Easy task
Beside Mini series or Metro series there is really nothing that can archive the level of accuracy in the price range on the market , unless you want to spend $26 K for it .
If there was any better for that price I would have it already 
P.S check my Mini 2 showcase
