skylights off the shelf. Velux or alternate brands? One opening / ventilated one with blind

[smilesandsun]

Hi,

Any advice on good skyligths at a reasonable cost? I need a few, one has to have the ability to provide ventilation and one has to have the ability to have a blind. Ive looked at velux and they seem fine but I am hoping to find a cheaper alternative.....

thx in advance!

following with interest, want to add some more and have two existing velux with blown gaskets to replace
