I use WellsTrade, Fidelity, Vanguard, and TDAmeritrade.
WellsTrade does do dividend reinvestment if you want. You have to fax them a form on that.
WellsTrade does allow an overall portfolio view of your accounts. It has a view that is even better than Fidelity in that regard. It also has an account aggregation thing called OneStop which uses Yodlee to be able to look at all your entered accounts from all your financial institutions and not just WellsFargo.
The 100 trades a year is per account. That's about 95 trades per account more than you will need to use. You need to meet the minimum account value and have a PMA package with free checking to get free trades.
And surprisingly, WellsTrade let's you purchase without commission Vanguard Signal share class Index funds as well as Admiral share class of Vanguard non-index funds.
Negatives: Minimum account value of $25,000 or $50,000 depending on which state you live in. Virtually, no interest on cash sweep account. Account closing fees if you decide to leave WT.
For those that can swing the account minimum, WT is the best deal going. They do not do any advertising about it which contrasts with all other brokers.
A good place for more research on WT is Bogleheads Investing Advice and Info
I am not sure what you mean by "portfolio evaluation". Many folks use the Morningstar Portfolio X-ray tool. Maybe that's something for you to look at?
