Product review (5 stars): Best deal out there !
After researching the market  I chose to purchase this unit based on price, features, and free shipping . I was hesitant because the description was vague, but it turns out it comes complete with regulator, commercial tap,misc o-rings & bits ,large locking castors and 5 lb co2 ,  the tap tower is black and 2 1/2 in dia.  it is predrilled for a 3inch dia upgrade , the tap valve itself is a" perlick" look alike . the unit cooled down quickly runs about 2 degrees cooler than set  and is extremely quiet  . looks elegant enough to show off in any room in the house.
