Agree with Bill.  I use PTO; with Lacerte under the hood, it's quite a capable tax product and it being cloud-based is a plus.  Nevertheless,  there could be a steep learning curve for data entry and frustration with the lack of user-control in some respects (compared to its higher-priced sibling).

Try negotiate the rates for PS with Intuit if you can.  Don't know about Drake (which doesn't work well with international returns) but ATX is quite open to fee negotiation - even if you don't switch, you'd know your baseline.
