Your choice of Voice router

Hi,
If you had an extra 2620xm, 3725, and 2811 . What would you pick for your dedicated CME router and why?
I am wanting to re-wire my lab at home as I start to get into ccna voice, and figured I'd ask your thoughts on this.
I have a 3550 poe and a couple 7940g phones, I'll probably pick up one more 3550poe switch and maybe a 7960 phone as I get more into this.
Thanks

I need to do more reading, but this is something I want to play with for sure.
