As carly and baggybear i have a bag/holdall (primarni too) which fits in solution, gun, hose, machine, record cards, shower caps, solution (fitted in so it is always upright) barrier cream, sticky feet, disposable knickers and a mat & towel (keep spares in my car) and my tent in its own bag. Really easy to carry!
Oh and don't forget an extension lead is a must! Cx
