Well, I'm sure you've heard the saying "you get what you pay for". Sadly this is true with car modding.
You can certainly purchase Monroes or another autoparts brand shocks/strut, but depending on their quality and your road conditions they might not last that long and you'll be in the same boat in a couple years or less.
Yes, there are very expensive options out there, but there are also more "budget friendly" name brand options. KYB has some options and Koni is having their big spring sale right now.
You can pick up a set of their STR.T shocks/struts for $329. That's roughly ~$80 per unit. If that's still high the KYB Gas A Just's run ~$250.
It's your car, and more importantly your wallet, but I would recommend spending a little bit more to get better quality products.
