Best IB/FCM to execute electronic options

I am looking for a IB or FCM where I can trade electronic Emini SP and electronic US Bonds options - where I can enter the orders via my computer - any recommendations ?

 

no idea.. if you find out let me know!

 

www.interactivebrokers.com via their workstation software or via your own software talking to their api.

 

any other location besides IB - they appear to have to many side issues
