Lower control arms questions

Hi,
First post here.
I bought at 2013 Sequoia with 175K miles. I had an oil change and brake job done for a great price at Toyota of North Austin. I got a full maintenance check done there too. They let me know that both lower control arm bushings are leaking and quoted me $2446 to replace the arms.

Would something like this be good?

If not, is there a recommended kit that is as good as OEM but cheaper?

Is OEM better?

Should I avoid used parts off of eBay for this type of wear item?

Is there anything else I should replace while getting this job done?

Thanks for any help!

 

OEM only, for lowers. Freedom off road has some good prices, I got my uppers from them.
