Non Fluro Hoses (yes - but then VW use N/F hoses all over the breather system on the GTI - seem to last fairly well)
Ordinary Jubilee Clips - sorted by £8 worth of OEM clips.
Smaller tank - BSH Larger variant available from BSH/Dubtek (as per the recent huge GB) for the same cost.
No level check - BSH has easy level check available - Dipstick level check on larger variants - simples.
One huge plus is the way the BSH is emptied in situ.......... Very handy.
I do agree with the use of plastic elbows etc, but it is a few pound to buy brass versions from a plumbers. Forge outlets on the breather plate look to have very small diameter.
To bring the BSH 'perceived lower standard' up to the perceived 'standard' of the forge is going to cost £20? then you stick the rest (circa £200) towards some of Shell's finest. the forge variant does look very well made, but not £200+ better, value for money I think BSH wins hands down.
I know where my money would be spent, and as ever this is just my opinion.
....
At the risk of getting into a lot of detail [T_T style!], I agree that the BSH is very good value for money but at not quite the extent of cost differential of the £200+ you state.
Non Fluoro Hoses - OEM isn't always best and can often be improved for longevity.
OEM clips are painted steel and quickly show signs of corrosion and you need to buy a special tool to undo them safely without potential injury! VAG are now changing their OEM clips AFAIK.
BSH's
equivalent size tank system costs £190 in the US to buy singly (not via a huge group buy). Add UK tax and shipping?
BSH level check is good but slightly less convenient than Forge's sight-glass [I'm getting pedantic here!].
Forge tank can be emptied in situ too - The fluoro hoses are very flexible. However, I would recommend removing and cleaning any catch tank every time you empty it to get rid of all the gunk and keep the functionality tip top.
But don't get me wrong, the BSH offers an adequate cheaper alternative. I had a BSH system, sold it and 'lost' money, and I was happy to pay much more for what I personally much prefer. More than one professional mechanic has, totally unprompted, stated what a difference in quality and fitment. Forge's washscreen filler is a bonus but has to be priced for.
As I said before, it's good for the consumer that we have a range of alternatives
