If you commute from Parker to Denver, is it worth it to use E-470?

I grew up in Parker and it has grown so much. It used to be a quick trip up Lincoln Avenue to the highway or even down Parker Road to Arapahoe and then just west to I-25. I personally think E-470 is worth it since it is a straight shot with no lights and much less traffic, but it's just crazy how the prices have gone up so much since it opened. In order to get a discount you have to place it in your car, typically on the windshield. I have one and it saves 20% on tolls, but it doesn't work on a monthly system. You pay per toll. They charge your credit or bank card for a starting amount of $35 and when your account drops they charge it again. From Parker to I-25 you can save about 20-25 minutes but once you're on I-25 you're back into the thick of things. If you're heading to the airport though, it's great as there is no traffic, the roads are typically kept very clear in winter, and there are no lights or stops. In my opinion, it's worth it.
