I use Fidelity and have my portfolio as follows:  
  
 45% FZROX, 35% FZILX, 10% HDV, 10% AGG. All set to dividend reinvest. 
  
 No commissions to buy any of those funds through Fidelity. No fees on 80% of the portfolio. 
  
 I don't want any of my tax advantaged money going to commission or fees because it can't be easily replaced. Capital preservation in my IRA is extremely important to me.

The only thing is that I plan to sell covered calls against my positions very frequently--both as a hedge and to increase returns.  
  
 Schwab is cheaper than Vanguard for this (for low accounts), but I'll need to compare against Fidelity for that too.
