As you can see, those are hardly "similar" specs. In addition to buying local with 1 year local manufacturing warranty, I'd say its worth an extra $90, still up to you to decide though. As for other places to buy from besides Aliexpress. There's right here from forum members (Try a search in the garage sales section),
DX and
Lazada Malaysia with possibility to get a cheaper deal through discount codes. Though better support lowyat forum members...

Oh, thanks for the detailed comparation between both, definitely minix is a worth buy over the another one. Will try to check it out the price in here. Thanks again!
