Which Starter Kit?

I decided to get into this hobby to keep using my mind for something useful! In the late 70's, early 80's I designed, built and programmed (assembly language!) 8085-based micro-controllers. I'm looking for a reasonably complete starter kit for a more modern micro-controller. (I have a lot of RC servos on hand for projects.)

Amazon lists a very complete kit with a lot of parts I see as useful from someone called 16Hz. (http://www.amazon.com/16Hertz-UNO-Ultimate-Starter-Breadboard/dp/B00KGF0ZD6/ref=cm_cr_pr_product_top) The price looks great but I have some concerns about the quality. The lack of documentation is not really an issue as this website is great. The alternative is the "official" Arduino starter kit (http://www.amazon.com/Arduino-Starter-Official-170-page-Projects/dp/B009UKZV0A/ref=pd_cp_pc_0) which has fewer parts and is lacking some really useful ones (rangefinder, accelerometer & gyro, etc.) and is a lot more expensive.

I'm looking for some advice, preferably from someone who has used the 16HZ kit.
