In reply to George1924:
Learnt and did another trip with Jagged Globe who were excellent

I've also done alpine climbing with ISM who do ice climbing

As said above, I think the main thing in getting best value for money, is to actually spend more money and go to the Alps if it is waterfall ice you want. You are much more likely to get good reliable conditions and places like Cogne have loads of easily accessible spots which minimise walking times and maximise time on the ice. Loads of easy stuff and harder routes as well if you progress quickly.
However, this reply is based on you wanting to climb waterfall ice. If you just want to climb harder and more technical spring/summer alpine routes then focusing on improving mixed and rock climbing might be better.
Be careful as well, once you climb waterfall ice you will be hooked. I strongly recommend going to Canada (Banff area) and Slovenia when you are hooked.
