Thanks for the kind inputs everyone!
Peter:
I do have the intention of bringing the full kit along with the coolers actually. But I have seen group buy organisers getting flamed over fitment problems and also the inconsistencies of the "kit" as one or two parts getting missing etc. In all honesty, the coolers and piping kits come from China, therefore I do hope buyers from other group buy/s realise that sometimes discrepancies do occur when manufacturers send to any group buys organisers their orders. Such things, although the onus are on group buys organisers to ensure the customers get what they pay for, sometimes its really outta organisers control.
However, participating in group buys have their own merits too. Such as lowered prices, competitive price wars amongst group buys organisers and also an alternative to mainstream brands which usually cost far over most of our budgets.
I personally do not speak for anyone, I'm just offering my .02cents worth of views of how I see it.
