Probably more along the lines of a $20 bottle class, again...if lucky. Still a great deal though. 30 bottles that would sell for about $20 is $600 worth of wine for the cost of a kit. If you go to labelpeelers.com you can get high end Wine Expert Eclipse kit mentioned above for around $125 delivered.
It is more about the hobby and playing around with how you make your wine to see what you can come up with than anything else. If you want consistent, $80 bottles of wine...I would buy them already there.
