Since you specify US$, I'm assuming you are based in the US. Walmart had special offers of the at the moment probably best-suited OpenWrt device there is only a few days ago, where they sold the Belkin RT3200/Linksys E8450 for 60US$. If you can get that, it's definitely worth the 10US$ premium. Check https://forum.openwrt.org/t/belkin-rt3200-currently-60-at-wa... for pointers.
