SoCal,
I too use tight stops as I tend to only enter high probability setups, although they are mental as opposed to actually placing them and involve me at least initially watching Level II pretty closely.
Unfortunately Laser does lack good stops, they have a client-side stop system but I stopped using that after a single print went off 70c outside the market and took me out of a nice position and also put me the wrong way round (was short, it took me out and put me long!). It also relies on my internet connectivity being 100% so I don't feel safe leaving the PC and stepping out.
That is my major gripe, although I gather they are working on server-side stops I'm yet to hear anything definite and have found quite a few other users pissed off about this. You may want to question them about this. It's not like I have any ulterior motive (e.g. pressuring them as I want this!)
It's weak in charting unfortunately IMO and for this I *gulp* rely upon eSignal. I greatly dislike eSignal as a company for their terrible support and programming, but unfortunately love their charting when it's working. Contradiction? I know. One day I might get around to writing my own platform perfect to my use, but for now am focusing merely on the trading!
R.e. Fees etc, you have several options as there are quite a few prop firms who use Laser too. I found a site a while back created by a user here, see this post:

I use an X-keys keyboard, my trading is primarily 99% liquidity taking and literally just hit one button to enter a limit order of whatever I want and execute it.
One other note: IB's "SMART" routing is server side, Laser's is not or so it appears. If you have high latency by being on another continent or some such thing this does mean you have to be a little more pro-active in learning about routing.
Hope this helps - and this is only my somewhat limited opinion so you're probably better waiting for others to respond with knowledge of more platforms.
