cut-throat on 1-100 Strike Freedom...some shop is selling at RM150 at eBay.

the good-old RX-78-2...i think there is many version of MG itself.
Forget about the old version 1, which is RX-78-2 and G3...not worthy.
Version 1.5 either u can get the RX-78-2 or Char ver, basically the same. this kit is a great improvement over the version 1.
20th annivesary version--u can get it if u dun plan to paint and u like chrome gundam.
ver-ka, it look more "square" and "muscular". no much comments on it.
then Plamo-Kyoshiro(typo) version or Perfect Gundam, this kit is selling very cheap at HK(if u can get it). This kit although had less panel-line and posebility but is the closest match to the anime version, or the HGUC version.
the latest of coz is the OYW-version, the posebility got improvement over the shoulder, waist and feet area. panel-line is superb!! the manual instruction is Full-Color not more black-white. but this kit dun have beam javelin and core fighter.
as bang for buck-i think ver1.5 is great. if u got extra-bucks then OYW-ver is u choice, u won't regret it.
Agree...ver 1 MG RX78 is the very first kind of the series, really don't worth buying now, unless you want to open a MG museum, then is a must buy, hehheehee......
Ver1.5 when compare to Ver KA i personally choose Ver Ka as ver 1.5 one look thiner and not that LengZai to me lah, some more KA one got more sticker leh.....but 2 of them also don't have movable fingers, right? their finger setting is 1+1+3, right?
