Yep, camber bolts definately have a tendency to move around, even when still tight, so loctite won't help...
What sort of car is it for? I assume those strut tops for $330 were only camber adj, not caster?
There are a few options:
1. As Ballistik Dude said, just slot your struts, then weld new washers in the said location... I did this to both my civic rally car, and charade tarmac club car, and it works well. Albiet not adj, and only good for as long as you have the shock... Advantages, cheap and easy...
2. Get universal strut tops, and drill holes where you want the shock to sit... Advantages: Cheap when compared to fully adjustable tops, allows you to dial in caster as well as camber, and tilts the whole shock not just the hub... Disadvantages: Not adj and more expensive than either option 1, or camber bolts...
Matt Dyne just bought a pair, have a chat to him how he plans to use them. They're either available in solid bearing, or urethane encased, and either bell above or bell below... $225

3. Fully adj strut tops... Advantages: Everything

Disadvantages: Cost...
