Help to decide - Bi-fold doors and lantern lights

[Bmac3]

Has anyone fitted bi-fold doors and/or a lantern/roof light recently. Just wondering which brands of doors are best value for money and whether anyone has had a flat roof light fitted as apposed to the lantern type effect. The doors will cover roughly 6m and the light is about 3.2m x 1.8m. Any help would be appreciated and likely to cost a fair penny!!
