I say buy two cheap ones if the budget is tight. You'll find having 36 grit and 80 grit both ready to go without having to stop and swap pretty dang handy. And you won't notice the difference all that much cause its not the grinder its the disks that do all the work. I ran a HF Chicago tools and my De Walt while stripping my cab. Its all about good AO disks to me.
