For right at the $100 price point I would suggest either the Leupold Yosemite 8x30s/6x30s, Vortex Raptor/Eagle Optics Raven 6.5x32s or the Bushnell Legend porro 8x42. All offer excellent optics for the money!

I do have some Leupold Cascade porros up on Ebay but they are a little more expensive than you are looking for.
