I would if I were u!!!!!!
There is a huge difference in the quality of the cabinets between what I build and the average kitchen shop (Kitchen conection, Impala, Ikea, Harvey Norman)
There are different quality melamines. Some that absorb water like a spong and some that take alot longer. We use a higher quality board!
There are different ways to make cabinets. Some companys use knock down fittings and 4mm backs stappled on. We use 16mm backs and glue, nail and screw everything! We offer cabients built to the 1mm. Most companys offer cabinets in 100mm increments.
Some companys use cheap and nasty plastic legs to support the cabinets and stone tops. These compress and move. The false kick front also shows gaps and swells at the site of water. We use solid ladder construction kicks made from plywood that never has any problems with water and supports the weight properly.
There is some really nasty paint(polyurethane) jobs out there. The paint is to thin and to hard. It wears and chips easily!
Materials were alot cheaper in your mothers day. A kitchen built thatway would cost a bomb and no one would want to pay for it.
If you want to talk quality then those cabinets of your mums didnt have any backs, the drawers didnt have runners or softclose and the doors were swung on nasty external or butt hinges. The quality of the hardware today is far far better than what was available.
