Although it has been a while, I did use them at one time for accounts requiring the Alabanza panel. They provided me excellent, trouble free service. In addition, since then, they have improved their support coverage by contracting with hostworks.ca which provides online chat customer service for both sales and support. I have also communicated with Alex and found him to be very professional.
My only caution is to not use alacart (Alabanza's shopping cart) as it is proprietary and you will be in trouble if either you or successful move away from Alabanza.
