I bought something similar from west marine a few years back. It was acceptable for the money. I ended up using a track rather than a fixed point for the main frame. That way I could slide it back toward the sun deck or up toward the cockpit depending on need by chaning tension on the straps. When I laid it down I slid the end of the frame all the way forward, which let the bimini lay back behind my rear bench seat. I just made sure that the frame fit was inside the point where my windshield/fairing met my gunwales/gunnels.
