yeah, there is quite a big crew of sentai roleplay toy collectors. i collect a lot of them myself, but unless you are into doing cosplay stuff, most are pretty lame. just replicas from the shows that have some very basic sound n' light functions. i don't do cosplay stuff, but i like super sentai, so i find myself collecting them (loosely. only if i can get a good price on them). i have a few "played with condition" early american power ranger morphers. the time force badge morpher is pretty cool. basic lights and sounds, but the spring action mechanism is cool. i have a few more that aren't worth shedding light on. but, my favorite roleplay sentai toys, and probably the only ones i can recommend aside from the mobirates is the gekiranger toys. which is funny, because the whole gekiranger sunglasses morpher thing is SUPER lame compared to other shows. but, the wolf morpher is fun, if you get the official japan bandai version. the ratchet fliptop thing is cool. its a basic lights n' sounds toy also, but it looks amazing! i also recommend checking out the claw cannon. granted, it took awhile to grow on me, because the toys scale is waaaaay smaller than it should be, based on the show. but the overall look of the cannon (both show and toy) is quite beautiful, imo. and the LED lights function looks really stellar when engaged.
one last notable mention is the Go-Busters wrist morpher. great fucking morpher! again, lights n' sounds, mostly, but when triggered, it has a mechanism that lifts the glasses up and opens them up in a slow, spring loaded fashion. here's a "decent" review, if you can get past the annoyance of the "nice" review
