EGR bypass kit - which one?

[BigAde]

Thinking of fitting an EGR bypass kit. The stainless steel ones seem to be well thought of here and there are numerous sellers on Ebay (not to mention DMGRS here). Most of the advice I've found here and elsewhere relates to sellers no longer selling on Ebay.

Seems there's these options:
DMGRS - £31.49. http://www.dmgrs.co.uk/collections/p...aces-wav000160
(doesn't seem to come with gasket, jubilee clip, bolts etc)

Magic_Parts_UK £34.99 http://www.ebay.co.uk/itm/ROVER-75-M...-/141143689530

Magic_Parts_UK £38.99 http://www.ebay.co.uk/itm/ROVER-75-M...-/141211562280
(not sure what the difference between the above 2 are except the more expensive one looks better made)

myldanautodesignltd £39.99 http://www.ebay.co.uk/itm/FULL-STAIN...-/161226288994

x8rltd £39.99 http://www.ebay.co.uk/itm/Rover-75-M...-/321546070802

So, who would have thought it, quite a choice.
Anyone got any experience of these sellers and their products?

Thanks
