Hi Lance
There are undoubtedly many tanks that have SS coils but I'll suggest the Uwell Crown tank, version 1 not 2, as one of the most successful sub-ohm tanks made. I see today they have resurected it with a mini version for about $25. It looks to be identical to the version 1 full size tank with a shorter glass & chimney.
I was of course going to recommend you get the RBA for the Baby Beast until you said you don't want to build your own. You may want to rethink that as store bought coils tend to get harder and harder to find as time passes from their introduction and for the BB tank they are also pretty expensive. Rebuilding is not hard and you can even order pre-made coils which just require installation and wicking. There is also an RBA for the Crown tank.
Another thought is the use of power mode if you haven't already become familiar with it of course. I've never bothered to run TC on any of my mods even though they are all coiled with SS and all TC capable. One of these days when I have nothing else to do maybe I'll play with TC.
