Exsiting Business looking for first auto

Hoping this works. Ive been in the t-shirt and sign business for around 10 years, but recently have been full force on the t-shirts and have improved to the point where its time for an auto press. I was thinking about either a 6 color or 8 color press. Any opinions? My shop is around 1500 sq ft, so it will have to be smaller press. I really like what i see in the diamond back, but dont know enough about them. Any help would be great. Also something you think would be up my alley for sale let me know.
