Well, based on the responses above, I took the liberty of applying the data along with several algorithms and analytical formulations to conclude that the best answer is no,use the money to buy a lot of beer or your preference. If there is any left over then load books,brass,bullets,primers & powder would be in order

I have never trimmed pistol fired straight wall brass nor do I know anyone who does. You sound like your on track to a well thought out and capable setup, go have fun and enjoy it, you can keep track of your brass lengths if you like but will probably find no need to trim. If trimming is preferred, they can be found everywhere for every price. Good luck.
