Help deciding on a machine

I have been outsourcing my embroidery and am considering buying my own machine. I will need to do the same design repetitively. I will be embroidering several hundred items each month using an assortment of 3-4 designs. 4 colors is the most used on any one design. 3x3 is the largest embroidery area I will need. What machine would you recommend?

As another option I may keep outsourcing the more complex design and only do the smallest myself, so what machine would you recommend for a 2 color design?

Speed is important to me because of the number of pieces I will need to do. I have never used an embroidery machine so ease of use is also important.

Thanks for any advice you can offer!
