From what I found (when we were looking for a machine), the front-load ones seem the most durable looking. The only brand I recognised here was whirpool. They will, however, cost you in the region of about 3 thousand pesos (about 50% more than the same machine will cost in Europe). Even so, I've found that most electrical stores here will let you buy an extended warranty (about 3 years) for a bit extra so if you do go for something less durable looking, at least it'll be covered for that time.
We got a bog-standard gafa machine and it's holding up well...It's pretty plasticy so I can't imagine it lasting for years, but it is certainly saving us a fortune in laundry bills.
Also...be very careful to check the specifications before buying. We thought we were getting a great deal and ended up with a machine with no centrifuge (spin-cycle). It's worked out ok for us because we have a PH with a washing line on our terrace but would've been an absolute nightmare if we'd lived lived in an apartment and had to hang dripping clothes everywhere...
