Going to agree with the vinyl guys. Get good quality, spend a bit more and will last longer than cedar and still look better throughout time. Put up cedar or any other wood fence and within 4 months you cedar will still be inlace but will look like a dull great weathered crap fence. You may have good intentions about spraying a sealer on it several times a year but let me tell you; you won't. If you want a pretty, nice looking fence go with a quality vinyl because you won't pressure wash and seal your fence 2-3 times a year.
You dont have to seal a wood fence 2-3 times per year.
Mine has been up for 7 years, I have put a stain/sealer on it twice, and it still has a nice deep red look and beads water.
