They also going to release 1:24 size Tamiya Lunch Box too but unfortunately but doesn't looked tempting at rctech forum.

Don't hold back, get it before its gone.  Sometimes some Tamiya models comes seasonal. 

The reason why  i prefer www.rcmart.com is because its the nearest and most reliable r/c shop for Tamiya in asia that have proper pricing, fixed shipping rate and they have been around long before any establish rc shop online exist.  Their Tamiya models is directly from Tamiya manufacturer so their price is very reasonable with everything intact and their shipping much justified based on years buying from them.  If you buy at other online shop sometimes they stripped out those ESC that include with it and have weird surcharges.  Tamiya model price doesn't go up or down that easily due to their branding unlike china models. Plus their packaging are top notch, they know R/C enthusiast doen't like their Tamiya boxes got dented. 

The models already included motor and esc, so you'll have to buy radio combo, servo and battery.

*Oh btw you'll need to buy extra spray paints.

Here how it looks like when i build my Tamiya on this video here as i build my Tamiya Willy 2:
