Any home owner needs a good quality cheap sander around the house. These can be put away and not used for years but then all of a sudden, a job turns up and out pops the reliable belt sander.
The frequency of which you'll be using the sander is the number one factor in setting your budget. We really don't see much point in going out and getting a top of the range Makita sander if you'll only be using it once a blue moon. If you work in the joinery trans then you'll probably already be looking at one of the higher end brands like Makita or Ryobi. Machine Mart and B&Q are probably the best places to pick up these top of the range sanders for lower prices than other stores.
For those that don't use them that much, maybe you're doing some basic DIY, then there is plenty of choice out there. Try and look at the budget brands at Argos. They have a load of cheap sanders to choose from, from their own Simple Value range and many others. Wickes also have their own range and these are a slightly better than cheaper sanders. If the jobs you're undertaking at pretty big, a Wickes sander may be the answer. A good balance between price and quality.
The main uses of a sander are to smooth out the imperfections of wood. So whether you're refurbishing some doors, or floorboards, you'll need a sander of some description to do the job.
A decent sander will have interchangeable heads, or sandpaper to get the different grades so as not to damage the wood by using to corse of a grade when you get down to the fine sanding.
By taking your time and going through the grades in sandpaper correctly, you'll get a really good finish on your doors, skirting boards and floorboards with a good quality cheap sander.
