Definatly make the switch. You will find you get a lot more support from Matt and his team, they are really helpful and often you will get a response in a few hours no matter what the question.
After I was thrown out of the squid ( I am one of the gang of four that where a little too vocal about the changes squid forced upon everyone) I thought I would see a drop in sales but to my surprise after a couple of months I was selling more.
Dont forget they are supposed to be working for you, if you like think of the site where you are selling your models as an agent for you work, something which a few sites have forgotten.
Good luck
