I use Tanning Essentials as they supply to Moroccan Tan (which I use anyway) and also White to Brown ( I think that's what they're called?)
The machines are fab because for small machines at fab prices they really do the job, lots of options for speeds on the body of the machine and on the applicator gun itself.
Best part is you don't have to take it all apart to clean it, just spray water through it and it's done, as the needle is Teflon coated. I've had mine for 2 years now and it's used regularly and never had any problems. Clients actually comment on how little overspray there is with it compared to other places they've been. They also sell extractors and disposables eg sticky feet and barrier cream very reasonably. Hth x
