VT10,
I don't doubt that EGNT is a busy airport but you can avoid some of the 'holding' problems by being a little more selective with the timing of your flights.
I do agree however that the landing fees add a fair bit to the total price - especially if you chuck a few T&Gs in for good measure but you need to balance that against the time & costs of driving to the other airfields you mention (depending on where you live).
