Plus one for either waiting until late fall or finding a nice used one. I love maple and I love rosewood, but in my experience we are talking about two discernable tonal profiles. I have a RW F-55 ( the 6 string version of what you are looking at ) and I can tell you now I will one day own a Maple F-50 / F-55 new or used because it will sound different enough.
Quick Maple story: I was in Zoo music Garland, TX on Saturday picking up an extra mic before my gig. Also nabbed a well-priced NOS Fender Vibro Champ XD ( killer amp in the 5w category ), but I digress. A musician came in with a Maple F-50 that was well played but structurally in great condition - played beautifully as it should have. He told me the story about how a year ago he found it in its case at a Goodwill marked at $195... He said he dropped $200 on the counter and got out of there as quickly as he could. He also said he ran every light going home
