Not everything is what it seems. Always look at cost for aftercare and apples for apples.
Paying a little more upfront for a quality machine which manufactures will also support their independant dealers will provide longer term satisfaction and overall reduced cost.
Tell tale signs you are speaking with a website referral or an agent selling on commision based leads are those adverts asking you to quote a branch code, dealer code or providing a cheap price upfront which seems to undercut everyone else to make a sale.
Not everything is apples for apples!
Check installation aftercare price, on site attendance response to repairs, availability of spares to dealers and warranty exclusions and terms before signing!
