Cheetor's are definitely aplenty every where, but when I was in HK, I had a hard time finding a cheap Hot Shot. Only found a couple, both over HKD $200. Grabbed one at $230 (A$32) from In's Point Shop #221, which I was quite fond of.
That being said, as the G1 fan I perceive you to be, these three are easy passes, so congrats on your quasi-completion. There will similarly be a few skippable figs in United, such as G2 Prime & Lugnut.
