FWIW, I grabbed a couple of the Schumacher bits - a 750w inverter that I got for $20, and a few of the jump boxes/compressers that I got for about $31 apiece. I'll have to see how the batteries hold up - I know they won't be like my Jump and Carry, but for less than half the retail price, I don't expect it - they seem like decently assembled devices and are great for an occasional road trip/recovery function )like my wagon always was and my truck is turning into

). Also tossed one in Carolyn's car for peace of mind.
Thanks for the heads up.
