I bought this Chinese cheapie when I arrived in Phuket over 9 years ago, and have used it most days since. It cost 3,200 Thai baht. Add the basket and lights for another 700 baht, and I had a great commuter. The campus where I teach is just 1 km from my apartment, and I use the bicycle for most trips within a 10 km radius, sometimes a bit more. Beyond that I use my motorcycle; I don't have a car.
Nothing fancy, it has a steel frame, no suspension and just six gears, however the rims are aluminium, and it has good cantilever brakes. It is well used; I am on my fourth set of tyres, and have replaced the chain and sprockets twice.
