The stock struts lasted about 50-70k depending on your use. My rears were leaking by 50k and I did a re-do then. Those blew out at 90k (just one damn it) and so I had to either junk the car, go back to stock or go for the Coilovers.
You have many choices, God Speed, K-Sport Megan or B/C that are in market and easy to get. The Megans are ONLY for on Touring, trust me i found that out the hard way, the front brake mounts do not fit. Get them "with spindle" so you don't have to do surgery on your old spindles. There are also some called Godspeed but I have never scene those before but they are cheap!
They are easy to get eBay and other places..very interesting that there are some new entrants since I did mine about 3 years ago. The B/C's are the best built from what the speed shops told me, they are also rebuildable so you can put in a new strut if/when you wear those out.
