I have a friend of mine who has the oven dolly. I can use it if I need it, so I don't need to buy one. Most time, however, I carry a series of 5 gallon buckets and milk crates, along with 6 2X6's. I can usually get the oven out, twist it a little, and get into the back to change the non resetable thermal fuse. The dolly does do a nice job however, and if I can get one reasonable I would probably buy one.
