The new TL looks very smart and the addition of the System-X piece for the hose reel is an excellent idea. (What type of glue did you use, please? Epoxy twin-pack?)
I must admit the possibility of buying the new TL and two or three pumps next year (well, one anyway) is becoming more likely, but what do I do with all my 3880s if I do buy 2 or 3 of the new ones?
