G1: Which DVD Versions to buy?

Hi,
I have recently had the transformers spark ignited and was after the Generation 1 DVDs however there seems to be loads of variants and am getting a bit confused by it all
I am wanting the whole Generation 1 and possibly the Takara ones although I'm not 100% sure how they fit in. I've found on Amazon these two:
http://www.amazon.com/TRANSFORMERS-Generation-G1-Episodes%2B-Secondary/dp/B000BP80ZQ/ref=pd_bbs_sr_10/104-8181888-3800730?ie=UTF8&s=dvd&qid=1188672830&sr=8-10
and
http://www.amazon.co.uk/Transformers-Takara-Complete-Collection/dp/B000TR6B8Y/ref=pd_bbs_sr_1/203-6346768-6876765?ie=UTF8&s=dvd&qid=1188674608&sr=8-1
Can anyone help me out?
