Like zog100 said: they've been around for ages - just moved to Castle Hill in the last couple of years.
They're good. Prices are good, staff are friendly. I've seen them at most local tournaments I've dropped in on. Dunno what their mail order is like 'cos I usually go in person.
Hobbies in the Hills is still around too (they've also just moved - only about 100 meters though). They are both near each other so it's a good spot to visit.
