The reason none of them have the reverse function is that they are based on old technology (TM21) which never had that function. The TM31 is still heavily patented that they can't copy it
is there a link, catherine? my friend is well and truly over her TC, and if i didn't know better, it is a strain on our relationship. i can't say a thing about what i've done with the TM, because as you could imagine, she's all daggers! personally, while the TM costs more than the TC, i still don't think the TC is cheap - it's still a lot of money, so whoever spends it has to get it right. i don't care that they may replace the butterfly or whatever - i couldn't be bothered by an inconvenience like that. but in the end it's an individual choice.
thanks, faffs.to be honest, i think the TC people will end up still wanting a TM at the end of the day. i know i'm lucky i didn't have to make a choice, but i'm more inclined to save up for something i really want than make do with something not quite what i want because i know i'll still want the first thing (made the mistake too many times, so only go for the best these days, or go without). TC is definitely expensive for what it does.
