Photographer Dilemma (again)

you may already know that i'm having some issues deciding between two photographers. here is the lo-down.

Sam: 

pictures look great.

is charging us $400 for the dol, $50/h for a portrait/family shoot beforehand.

at first i wasn't sure about her personality through the emails, but the more i talk to her, the better. and she seems to really want the job of shooting the dol.

Carla:

pictures also look great.

is charging us $250 for the dol, $150 for 90 minutes for a portrait shoot beforehand. because the weather was nice, she offered us a small shoot for $50 of just Gemma, which we took advantage of on sunday. she seems nice, but a little hurried (maybe because she had a client right after us). 

i know what you're thinking... the obvious choice is Carla, right? but a part of me still prefers Sam's pictures just a teeny tiny bit more and i want to meet her/see what she is like, not to mention see the pictures she takes of Gemma. The thing is, she is only offering us the portrait session at $50/h if we hire her to do the dol (otherwise, it would be $190/h). 

but i can't do 2 more shoots before the dol or else i'd be out $200, $200 that i could spend towards the day itself. besides, what if we do the portraits with Sam and decide we don't like her? then that would cost us $190!

oh boy oh boy... why is this so hard? what would you do???  it's like i know the easy solution would be to go with Carla, but i am just so curious about what could be with Sam...
