I stopped buying X-Wing after wave 8 ...
Aside from an overabundance of "early mistakes" (aka, buying too many X-Wings, Ties, A-Wings, B-Wings, and Interceptors), I feel like conversion kits will give me a whole new collection of ship dials & cards, none of which I own now , all while needing to simply trade-up those early models I have too much (or even simpler: play with proxy ships).
Now onto trading those extra figurines ....
