Deciding on the all important LED lamp-OPI or Gelish?

So I've just started out doing gel nails using mainly OPI gel colour and some gelish. I've got an led basic lamp at the moment and it's just taking forever. I did a set of gels today, polar bears and the lady has message me saying the Bears nose has come off! I can only assume it's because it hadn't been cured properly? Any ideas?
So I really want a more reliable lamp! I am edging towards the Gelish one more as the OPI one looks awful!

Any advice? Xx
