Re: Going from Fuse to Circuit Breaker
The first thing to do is check with your local building dept. In some areas you can replace the panel only, others require bringing the electrical system up to current code when the panel is replaced. A 1500sf house probably doesn't need a 200 amp service unless it's fully electric.
Considering the age of the house you may need a new meter base, new drop from the transformer, new SE cable and possible a new transformer to upgrade to 200 amp. That could add significantly to the cost.
Decide what you want to do and get several quotes. Be sure the quotes are itemized so you can do a proper comparison. One quote may be for labor only the other include the panel, breakers, etc.
If you do have Al wiring you will need to get someone familiar with the proper techniques for Al wiring.
