At that price, stay local....Craigslist, pawnshop, garage sale...ect. No shipping cost.
I have a pair of Infinity Entra One's that are excellent for the money. They originally sold for ~$400 MSRP, but appear on ebay for <$100 now. Excellent low end for a stand mount, and once broken in they're very good.
If your or anyone else for that matter live around Huntsville,AL. I have a pair of EPI 2 ways w/8 in. woofer from early 70's. They have good tonal balance equal to about the Infinity Q series of the late 80's and heavy. $25 and they are yours. I bought them from a secondhand store. Replacement parts also available for these, not that they need parts.
