I was in the same boat. I made a cable adapter, which is very easy to do and I kept my existing 2413S. I did have some problems using instructions listed elsewhere on the forum, but reversing the Tx and Rx wires took care of it. If you have any doubts about your ability to fashion such a cable, UDI sells a premade one for a nominal fee. At some point down the road, I'll probably get a USB PLM but I'm in no rush. Also, have a whole home surge suppressor and highly recommend getting one - not just for eisy, but many minor intermittent issues were resolved by adding it.
