I use a Tweezerman brush for my shave. However, I use a modified version of this technique for pre-shaving prep: http://badgerandblade.com/vb/showthread.php/9745-How-to-Pre-Shave-Prep.
I use my fingertips and massage the area to be shaved, instead of a brush on the pre-shave. Then, I use hot water in the shower to rinse, rather than a hot towel.
