I would invest in something that will last more than a year....it is a bit tedious to install...
It is a bit of work to install (especially since I mostly did mine by myself) but "investment" is a good word for it. If it'll hold up a few years (they say 7-10 years in high UV environments, if properly installed) then it's worth it to not have to worry about fussing with it for a good long time.
