The Cab1L and base combo can be had for $215, thats over $100 cheaper than another 990 set.
I've seen prices from two "well known dealers" on the 990 for $339- $349.
And so we're clear on this. Once your 990 comes back from Lionel you can disconnect the 1L base and store it away.
The Cab1 L handheld will communicate through the 990 base as well.
Maybe its me, it seems like Lionel still hasn't gotten the "bugs" out of the 990 system, we still see posts where this or that failed.
I've been using my old 1.4 base from years ago, turned off the charger when I took it out of the box and use energizer rechargables on a seperate charger and have had no issues. ( knock on wood) Even dropped the handheld on the concrete floor.
I have yet to even update the software. It ain't broke so I'm not fixing it.
The cab1L is a simpler system, no touchscreen, no backlight, multi-function switches etc. less features...but....less to go wrong.
