Prices on kits in the Philippines are great, about a year ago when I went to Manila I located a very nice shop in Makati City in a mall complex that was stocked literally to the cieling. The prices you got sound about right, the real trick is getting them home. Fortunately, I’d only brought a roll-aboard small suitcase and my laptop bag so I could max out my 70lb luggage limit with kits (also took up the spare weight with my travelling colleague) to get about 10 kits home at those prices. Couldn’t pass it up. [:D]
As far as the kits themselves go, I recommend you check out http://www.perthmilitarymodelling.com/ for reviews, they have one on each of the kits you picked up.
oh, and to keep this on the topic of armor… I dont build them much, do you guys assemble the hull, then paint? or keep the road wheels off?? I usually build planes
