Hi Kev,
I bought a UV lamp from flea bay for £10 and some UV gels for £5. It's just the same set up wifies use for their nails in salons. At £50 for a UV torch the guy is having a laugh.
I,m experimenting at the moment.
Much better than epoxy, less waste, no smell, no yellowing,far less drying time (3 mins with a 9watt lamp).
Paul.
