diane,
Although I'm by means a tire expert, I did a search back in Feb and here are a few tires I came up with all of which are a lot cheaper than OEM. I for one can not afford the $2,000 for the OEM Michelin's every time the car needs tires nor the $484.00 I paid for a replacement OEM tire.
You will give up some handling with different tires, so you have to decide if the $1k savings for new shoes is worth it to you..

As it was mentioned above, the OEM tires are Z-rated. IMO unless you plan on driving the car at very high speed, say 100 mph plus for an extended period I would not put out the extra money for Z-rated tires.
Here is the "MAX" Speed for each speed rating:
S = 112 mph
T = 118 mph
H = 130 mph
V = 149 mph
Z = Above 149 mph
I agree that you need to be careful who puts the new tires on your wheels. I would have them look at them before letting them start work and note on the repair order that there was no damage before they started.
Good luck in the tire search and let us know what tires you decide to go with. Oh, Something else to think about... if you do purchase the tires through Discount Tires, I "highly" recommend the road Hazard Insurance. They have changed out several of my tires with no questions asked... including an off road tire on my Jeep.
