I took the plunge on a Topre recently, and I have no regrets, even paying full price on a student's budget. My rationale was that my work pretty much has me at my computer all day, and as such, my keyboard is one of my most-used possessions. So I figured a premium item is worth the investment even if it only makes me a few percent happier. There's a theory of personal spending that says that you should spend your money where you spend your time---investing in a better mattress, office chair, keyboard, or whatever you use every day is (the theory goes) a wiser use of money than for something you rarely use. And your keyboard sounds pretty important to you---more so than to most of us here!
On a less philosophical note, my Topre replaced an MX Brown board (Rosewill) that I found to be quite loud in my quiet shared office. The switches aren't loud of course, but I found myself bottoming out with a consistent CLACK. That is probably in part due to the Rosewill's plate-mounted construction. Maybe I would have eventually learned to stop bottoming out, but I found the Browns to have so little tactility that I'm not sure I would.
Compared to my one experience with Browns (note that I've only tried the one Brown board, and haven't tried Reds), the Topre is for me quieter, more refined, and a purchase I don't regret.
It's true though that it all comes down to personal preference. You can read other peoples' opinions all day to try to rationalize your decisions, but in the end you need to find out what works for you and be content with that.
Good luck with your decision!
