Andrew,
getting the tube now is a lot easier than later when your throat is raw from radiation.
To PEG or not to PEG has been discussed heatedly here in the past, just check for it. I had one and was lucky that I did not have to use it much but even in retrospect I would get one again.

As far as the peg belt is concerned... I could not get a picture of it. Clearly taping the thing down is a pain and not a long term solution. However before you go and shell out $$$ consider this: an elastic bandage does wonders and if you cover the tube totally, prevents snagging.
