There are posts with foam inside the gear housing, clumped grease, people breaking the machine modding it, spindles failing inside a year, and some just.. not turning on out of the box. If you're doing this professionally, no I do not understand cheaping out the tool that will bring your paycheck in.
Instead of disassembling a tool to repack grease, flip switches around, etc, just get the 7424XP or GG that will work for years with no complaint. The race to the bottom never works out well for anyone in the end. So, no if you cannot afford an extra $60 to ensure you have a tool that will last and do the job for years on end, you should probably rethink how you do business. Fact is no one had a problem with the PC/GG until 60$ knockoff came out.There is no redeeming factor in this machine quality wise over established professional tools other than that it is CHEAP.
