I'm not sworn to the SV brand; they were just reasonably priced and I remember using them in school and being pleased with the quality. I'm trying to keep the budget around $500 - $1000, but I'm open to suggestions. Thanks!
I can't answer the question about which kit would be better, but I would like to offer you a number of things to consider when you are making that evaluation.
Although getting a kit is often a quick and inexpensive way to get a lighting setup, you will almost always get a better result by building your light kit yourself. Here's what I mean:
When I started looking at lights, I became convinced that continuous lighting was the way to go because I was having trouble visualizing how a given lighting setup would work. The more people I talked to about this, the more I discovered that continuous lighting would limit the applicability of my lighting kit. My decision was to get two moonlights, some pretty stout stands, and a bunch of sandbags. I started with a softbox, a strip, a reflector, barn doors, and a grid-spot. That got me a long way and I have tons of excellent shots where I don't feel any more light was necessary. (The moonlights came with umbrellas that I've never felt compelled to use in product photography.)
However, after shooting with variations on the above setup, I later decided to add a boom with counterweight -- that gave me a lot of options in terms of light placement that doesn't get in the way of the shot. I also added a beauty dish because it's so versatile in terms of light falloff and it can be modified with a sock to perform as another softbox.
As the demand for white backgrounds became an issue, I added two more flash heads for background lights and two softbox modifiers. These can be used with reflectors for directional light or the softboxes for a more diffuse light on the background.
The point is, I didn't know exactly how I would use the lights when I started building the kit so I added slowly, evaluating what was missing carefully in advance of adding new gear. The decision to go with studio flashes was, in my opinion, one of the best ones I made. I can't stand a hot set and neither can some of the stuff I shoot, for example food or plastics.
Good luck with this!
