Help- rough ride, Car rides really rough Options

[Teblhasa]

I am having a strange problem with my car. Whenever I hit a bump/pothole/crack in the road, depending how fast I hit it (usually over 20mph), the car skips to the side instead of bouncing over it. It also have a very rough ride and I swear I can feel even the pebbles on the road. I got new BF Goodrich tires last year to factory spec and my mechanic couldn't find any problems with the car. He suggested the ride was rough because its a small car, which is a bunch of bull. The ride is slowly getting worse and I don't know what to do, and I might end up having to sell the car because I cannot bear to ride in it. Any suggestions would be greatly appreciated! I am guessing its the struts, even though my mechanic swears they are fine and so is the alignment. If its the struts, are there any good but cheap brands of struts out there?

I want to correct my second statement- I never take speed bumps over 5mph! The other bumps are usually bigger cracks in the road (I live in MN and the wintertime murders roads!).

I had my tire pressure at 32, as the manual suggested, and then my friend was telling me that was why it was riding so rough, so I lowered them to I think 28. I think I will put them back to 32 today; I know underinflation is a bad thing. Especially since its nicer out now, and it will help the gas mileage greatly!

The census says its the struts so I will have them replaced with KYBs. I don't know how to replace them (I am an auto body person, not very mechanically inclined) but I think I will buy them and have a mechanic put them in for me. What's the best, cheapest and quickest place to buy them, online or in a store?

Thanks!
