With all the available parts suppliers out there these days, I would guess that the plan packs would do well.
I'd rather spend $12-$15 for a plan pack and the same amount for the kit in parts and build a quality product.
Verses a kit that plagues you with headaches to build and only lasts a few flights before landings does it in.
Or the trips to and from the launch area.
You have to remember when buying from Apogee thou, you are paying a premium for services available for free.
I haven't looked, but if they are sold by other vendors, they may be cheaper else wheres.
I agree with premium service, but never understood it. I figure if you have a business you would want to offer premium service and your reward would be your customer base and overwhemling orders. Why does that have to cost more. I'm saying it should be a given.
