Ryobi is great for starting out. They're definitely not the best tools, but they're cheap. If you wear out something from them, you've earned the right to buy a good brand of that tool.
I've gone through a skoolie (school bus converted to an RV) project and now most of a house renovation with one 1/4" Ryobi drill and one 3/8" Harbor Freight drill and they're both somehow still going strong after five years of hard usage. I had bad opinions of both manufacturers before but not any more.
My experience with Harbor Freight power tools is a (corded) circular saw that works extremely well. I put in a better blade, and it rocks. I've had it for years and it shows no signs of slowing down. I'm not a heavy user but I've used it for quite a few projects over the years, including an RV renovation I'm working on now.
