The early one's were pretty poorly put together, in some cases dangerously so. This is probably because Mr foffa didn't know enough about bikes when he started his business and is basically putting his name on a bike for no reason other than he has the money to buy the parts, pay someone else to put them together and then sell them at an inflated price.
Recent one's are fine. (If maybe a bit expensive)
As Andy says if your friend likes the look of it and it rolls, it should be fine.
The issue with Foffa is, I think, that he sells bikes worth £200 for £800 and that most of them look shit. I'm sure @dancing james can correct me if I'm wrong.
If he's happy with it then he should go for it.
