Yes. The fee in my area was $2.50 a month last month, so this is a 60% increase. Not trivial. At this price however it makes sense to buy your own. I just got rid of an 8 year old 5120 last week, and I paid $50 for it initially.
At $2.50 a month it has a 2 year break even, but $4, almost 1 year and you are better off w/ your own.
Frontier $7 is the reverse Morris trust tax
