I use a higher end 4.5 " DeWalt, had it for over 3 years, never an issue, good recycling too!!
I built my table out of recycled material too. 2 x 5 square tubing, exreme heavy duty, easy to level and work on, the top is 3/4 inch MDF, with 14 g sheet on top. That makes it quiet when ya hammer out sheetmetal.
