I have a couple kits going now. WE Vintners Reserve Cab & Australian Petit Verdot w/skins... Both bulk aging. I'm new to wine making. I've done tons of reading... Must say I'm rather disheartened to hear my wine will most likely be an $8 bottle and at best, not much better... How does a home winemaker produce a good if not excellent, complex wine....???
I would say your kits with skins and oak, given some aging time, will certainly compare to $15-20 wine. You can do a taste test when yours are done and decide.
To Boatboy24's point, tannins, age, and oak will help immensely.
I have started adding a few things to my kits:
-Toasted oak powder in primary
-Fermentation tannins
-Cellaring tannins
-Finishing tannins
-Oak spirals or chips while bulk-aging in carboys
I have posted this link before, but the Scott labs website has a wealth of clear information on tannins they produce, what they all do, etc. I am still experimenting with which ones and how much. So far, I like the Tannin Riche but am also trying the UvaTan. They add a lot of complexity to a wine, whether red or white.
www.scottlab.com Again, they're selling tannins, so tend to discount time and oak as being effective.
I'd like to split some batches and try different tannins on each to isolate the results, but haven't gotten around to it. I know that their addition makes the wine much better, and they aren't terribly expensive. However, my LHBS only had the big bottle of "TANNIN," without any explanation of what kind it is, so I had to mail order.
The only thing I have not used is liquid oak - primarily because it reminds me of Liquid Smoke, which strikes me a weird.
