No experience with finishes yet, but I do use UV resins pretty regularly.
I have a jury-rigged UV station, consisting of a couple of 395nm UV party lights from Amazon, and they get the job done - with up to 3/4" pours, a few minutes under the lights is enough. The light were about 35 bucks after a coupon and shipping.
That said, if the sun it out, I just pop the pieces outside and come back to them later - 5 minutes, 10 minutes, or whenever. For bigger pieces, a sunny day might actually be more convenient than waving a light around, because there isn't a huge spread on those lights.
