I also like TASC, I have a great local rep. They also now allow debit cards for prescriptions, anything else usually requires an
EOB anyway. The cost depends on the size of the group.
The thing I like about TASC, and maybe others do this too, is that they will cover the gap between employee expenses and plan funding. For example, if a small ten person group was on the hook for $10,000 ($1000 per person) and all ten employees reached their deductible the next day, TASC would pay the $10,000 and wait for you to fully fund the $10,000 over 12 months (basically a 0% loan). Now the odds of that happening are low, but I've had it be a deal breaker more than once.
