I got transponders when they first were installed and few people had them. They were paid for after 3 or 4 trips. And now most electronic toll plazas here are full-speed bypasses versus getting in the stop-and-go line at a toll booth to wait and pay double. Illinois had its own transponder system, but now has reciprocity with many other states. I have no idea how Massachusetts is implementing this, but they are sure worth it here. Good luck.

but we have it and would hate to be without it. Even if you just use it a few times a year, being able to bypass those long toll lines and zip right through the fast lane is well worth the initial bother of acquiring one. I'm in Mass.
