For wine kits, you really DO get what you pay for. A $60 kit will make a drinkable wine, similar to a "Two Buck Chuck" in quality, while a $150+ kit with more juice (less or no concentrate), grape skins, better grape juice, etc, will make a wonderful bottle of wine similar to about a $25 bottle.
I make a selection of cheap and medium priced kits for our everyday wines, and then once in a while to a ultra-premium kit for special wines for aging.
The nice thing about all kits is they have excellent instructions, and if you follow their instructions exactly you have a guaranteed product. If you don't have a good result, they'll send you a new kit in replacement.
Make sure you have the right sized equipment. For a wine kit, you'll need a primary fermenter (generally a bucket, but can be a carboy) and a 6 gallon carboy for secondary. Siphoning equipment is critical as well.
