Bottom line is if you love the tone, and then compared it to others and still think this is the standout, you owe it to yourself to get it. There is zero assurance another guitar, even so-called "higher up" on the line will offer you any more enjoyment, let alone "better" tone which we all know is subjective. So I'd say buy the one now whose tone speaks to you now. If things change for you in the future, you can re-asses at that juncture.
BTW, you can buff the satin up to a semigloss quite nicely. Read up on it: easy and the result, while not a full/deep gloss, is very nice. I did it myself on a BT and a 410. This from a guy who likewise is not a fan of satin-fin bodies.
