Well, I dunno about stopping, prolly just slowing down.. after I've completed the US released G1 figures I pretty much have been buying just what I want. based on Goks list though I still have 11 figures to get, mostly the insignificant ones which really doesn't count for me ( those red and purple "erasers", the minispies, pfft) Granted that I want a lot of figures (G1 Jap and Euro)hahaha
, but I'm back to the old collecting routine before I decided to get the whole G1 series completed. Buying only the ones I want and skipping those that doesn't tick my interest. Also I'm quite patient to sit back and wait, if I can't have the toy coz it's too pricey (hello AM Elite!) meh...Which has saved me heaps enough for me to send more money overseas to my mum and help out in the expenses for the new house construction plus buying a lot of items for interior décor for that new house. 
I'm just enjoying the collection as it is.
If ever I did need to desperately sell the collection - it's the Bayverse first then the Unicron trilogy , then RiD next and then the Sealed doubles of generations. I won't touch my G1s if I can help it.
