Love our 4500 Husky. Have had it for 2 years now and works great. Doubt we needed the 4500 but why not? It's been a workhorse for me. The only time I had an issue is when I put the battery back on and neglected to completely tighten the nut on the cable. Tried to raise the jack and nothing. I was sure it had gone bad but I kept looking around and discovered the loose cable. Don't take much to not get good contact.
As for the Husky 4500. Go for it. Go big or go home.
