Sam's advice is sound.
You don't want to buy, and have to repair before the fun begins. Leaves a bad taste in your mouth.

Buy the one that suits your needs, or budget, and is sound and appliances work well (very important).
The people on this forum often have used for periods of time and all things need to be repaired at some time. We offer the help/knowledge for the repair.
