Hobao (ST Pro) and Hong Nor (X2 CRT) has cheap spare parts and they are durable, Xray is european but has expensive spares.
I recommend truggy as basher and racer, it has more ground clearance than buggy, its bit more expensive than buggy but can be used more wider than buggy.
For lipos and charges, look for Turnigy from HC.
Battery trays can be done by self.
Motormount from RCM.
As you live in europe, its easier to buy from EU country if you live in one.
www.jespares.com has some great deals, like Ansmann W3 2.4GHz radio, looks like Sanwa MX-3.
I prefer 4wd cars only (1:10, 1:8, 1:1).
If there is some hobby store nearby, then i would buy brand that they sell spare parts, so you dont have to order every single part from other side of world.
