I did say I have never bought from them but those who have give positive responses.
V2HW and GunplaSG both suffer from the same problems: good prices but limited stock. Gunpla SG stocks newer stuff and have them for good prices on pre-order as well. Case being the coming MG Blue Frame, Kshatriya and PG 00.
Local forum for gunpla fans. Best thing about this is any news of sales and promotions related to gunpla is guaranteed to be spread here quickly. Example being the 20% sale on Gunpla at BHG Bugis starting from last week.
If you're eager for information about Gunpla SG, you can contact VD, a member of the forum above. He's purchased from them and apparently, purchases above $40 comes with free deliveries.
