I must say despite it being able to fold flat it's not that portable. It's quite a bit bigger than I thought it would be even folded up. It's not something I think I'll keep in the van on a full time basis for that reason.
In terms of buying the cheaper version I'm sure it will do a very similar/the same job, but my philosophy on these things is that I tend to justify the extra cost using the following rationale:
1) Buy cheap buy twice
2) Better resale value if I decide to get rid of it
3) I would have buyers remorse if I bought the cheaper one
I managed to get a 10% discount on the snow peak kit by asking in the store, but I agree it's very steep for what it is. If you look at other snow peak kit the prices they charge are fairly scandalous (e.g mugs, backpacks etc). It's very well reviewed online though, time will tell if it justifies the price.
Also the drifta kit comes with the cross section stand for under the base plate that raises it up off the ground, something the snow peak one doesn't have in the kit (it's an added extra)
