Agree. Unless you do heavy offroading, you don't need expensive disconnectable links. Inexpensive stock links are fine.
Napa, Autozone, ebay, RockAuto.com, etc... Sway bar link or stabilizer bar link. I replaced mine with greasable links but it's not necessary.
It's straightforward to replace them yourself. You can use a pickle fork (cheap on rockauto.com) or you can remove the entire sway bar, place it on an elevated surface, & hit the top of the link with a big hammer to get the old links out.
The new ones just bolt back in their place. I suggest new grade 8 (12.9 grade in metric) hex bolts for the bottom of the new links, though. The torx head bolt are a pain in the ass to deal with.
I noticed that you found this while having your oil changed. If you aren't a DIY-type girl, buy your own parts & let a shop do it. Keep in mind that if a shop charges more than an hour for labor (at the VERY most it's a 1/2 hour job), find a new shop or get a buddy to do it for a 12 pack of beer.
