Ivanhoe,
My suggestion is that if you can afford the Brown, go that route. It's the Rolls Royce of custom, the only next step for you would be having Dane or someone smith a totally custom pistol.
If you want to save $1k, then join the TRS club. Wilson makes a wonderful handgun. I have all three. But the TRS says more about you than a CQB. You can always get a CQB, but you can't always "join the Club".
Another thought you may want to consider. Worst case scenario, you buy the TRS and want to try the CQB, the TRS will hold it's value and you trade it in. I doubt you'll want to, but your option will be there. The Brown's a no-brainer. That holds it's value, and whoever sells it to you will buy it back if you want to purchase a TRS or CQB after that.
If you haven't, you really should chat with Terry Peters and Allan Yoast. They are the two guys who know the technical details, can advise you best on retention of value, etc.
Good luck with whatever decision you make, you can't go wrong with the field you've narrowed it down to.
