I love this sander.  Nothing like a big heavy 4 inch belt sander.  I recently had to sand down an old workbench and make it into a nice kitchen island.  I had to sand down between 1/8 and 1/4 inch from the entire top.  This was the right tool for the job.  It is nicely balanced, the belt tracks perfectly, the dust collection system works perfectly, it has a nice long cord .  I loved using this tool.  It is a work horse.  It glides nicely over the wood and does not leave any gouge marks as some of the 3x21 sanders do.  Nothing like a big 4 inch sander for professional looking jobs.  I can't say enough about this Makita sander.  Any professional work workers would totally understand.
