Where to get info on different Lumedyne products?

[gl600]

Hey,
I have been looking to get a Lumedyne kit (used) and I can't find info on the older kits.
I was looking at the following two kits:
1) Lumedyne 400 Watt Sec Outfit 067Q Pack C1 Batt Charger - eBay (item 150466007006 end time Jul-20-10 12:14:47 PDT)
2) Lumedyne 400 Watt Sec Outfit 067 Pack Reg. Batt Charger - eBay (item 220635043879 end time Jul-19-10 14:42:25 PDT)
I want to know what the Q means. (One item says 67Q and the other just 67).
I went on the Lumedyne website (which seems out of date) and could not find what I was looking for.
There have been a bunch of Lumedyne products I wanted to research but couldn't find them on their site either.
Does anyone know where I can get info on older Lumedyne products?
Thanks

Look at the dg28.com web site, to see how good some of the older Lumedyne products are, and how to actually use them and select them.
