OK - narrowed down to a choice of two - comments?

In my quest to find non-dealing desk brokers I have come up with the following:

Tradex - for $25K guarantee a feed direct to interbanks plus $20 per round trip (trade). For $100K they will guarantee your capital.

Delta Trading - no minimum and apparantely give you Level II trading.

AC Markets - assure me no dealing desk - direct feed - minimum $5K to open a standard account.

Tradex = first choice at this point.
