Personally I have three, Kikaider, Yellow Gao Ranger and the recently acquired Tiger Joe from the Lion Maru TV series. I picked him up fairly cheap, in the 4,000 ¥ range, mint and never removed from the box.
Otherwise everything else goes together fairly easily.
The only other kit like assembly detail was the use of two faced tape (provided) to secure the chest plate to the front of the costume. Some incredible details highlight the beautifully sculpted boots and gloves. The Belt actually has a working buckle, not just Velcro. The sword is some sort of galvanized plastic with weight to give the impression of metal. No detail is spared and it's glaringly obvious that again, the Japanese just cannot be beat when it comes to making toys, in any scale. The details are so fine on this piece that it is hard to image they are even in the same scale as Mego's, appearing even smaller because they actually get the physical proportions right.
These minute details should make any fan of those terrible DC Direct 12" dolls weep and gasp, they are almost the equivalent of Hot Toys for this scale. A bold statement indeed. It appears the company no longer exists with an attempt to log onto their website redirecting me to a generic server page and all item listings on HLJ are labeled as discontinued. Based on the character output it appears the line died in the early 2000's. Research tells me they've actually been around since the 1970's with a very familiar logo, usually associated with die cast. In any case, if you've ever considered it, I can only give these pieces high marks, especially if they can be found inexpensively, but be prepared to do a little assembly work. Don't think I want a complete collection but I'd definitely live to pepper my cases with a few more pieces.
