Dear oh dear oh dear. It's about lifestyle folks, not machinery - at least that's what everyone whinges longest and loudest about on the line.
Take whatever offer allows you to enjoy whatever takes your fancy outside of the tube. Personally, I'm a TP operator, soon to be jet, but already wanting back on the TP ASAP because it has a significantly better lifestyle attached to it than the humdrum existence I can expect on my new toy.
As for your jet offer, I wouldn't work for that guy if you offered me a million quid and a no-holds-barred night alone with Kylie!
