I have the Novatron 1000vr with 4 lights. I use for on location portraits and I love it. As was said sometimes there is too much power, other times you wish you had a bit more. Easy to use and setup. I purchased mine used as well about 6 years ago and it doesn't see commercial (everyday) use but it is holding up quite well for what I do with it.
IMO I would try it then depending on if everything is working, buy it.....lock, stock, and barrel. Its a good kit to start with at the price you have listed.
