Strange, my previous reply didn't appear but it show in 'my posts', so here goes again:
Hi Simon, you'll likely get as many different opinions as replies - everyone has their own view. For what it's worth, mine are: 1) aluminium frame, pre-coloured (powder coated) if you want that. 2) safety glass - expensive but the only type that will last for many years and essential if there are children or accident-prone (!) folk about. 3) for a GH of that size you want at least 2 windows and 2 louvres. Extra windows and vents usually add significantly to the price and much more so with some suppliers than others, so cost these in when comparing.
