For anyone who may be interested: I have a GTI Light booth for sale for viewing prints. This is the model with the dimmer and its in A1 condition. Only selling as have upgraded to larger model. Asking $500 - new I think they are around $1300 RRP. This is the model with the optional side walls and dimmer included.
