I think people just don't want you to waste your money when it isn't a difficult task.
I had a major pipe and kitchen faucet damage situation when my pipes froze last winter, never did plumbing before in my life.
I spend an hour researching how to fix it, then went to the store, bought a torch, pipe cutter, copper piping, soldier, other odds and ends, and a new kitchen sink.
I fixed the whole thing for under $50 even though I bought EVERYTHING new. I fixed it that day. I may have the cheap brand faucet, but it wasn't a difficult task, and everything is working great.
I think people just don't want to see you spend too much when the cost of repair seems to be a major concern of yours.
