My biased advice to you would be to get a fully upgraded Hyper 8 Pro kit off of Ebay. You should be able to get something fully built with a few spares for under $700 from the states.
I run the following on my Hyper 8 without any issues/complaints:
Hitec servos (High end digital ones)
NovaRossi P5X (Several gallons already, and still runs like new)
Center Diff Brace for FR2 chassis
CNC Rear 1.5 degree uprights
Lunsford titanium turnbuckle set (All turnbuckles and steering linkage)
Carbon Fiber Brake Disks (http://ofna.com/forum/viewtopic.php?t=4614&start=45
Panther Komodo II (Med Soft)
OFNA UltraLites Wheels
Radio Futaba 3PM HRS
I have also performed all the mods suggested @ http://nitrohouse.com/Tech_Tips_for_the_Hyper8.htm
It is a great racing platform with a huge cheap parts availability in the US (Not sure about Euro parts availability).
If you go the pro kit route and need to invest in radio/motor/servos, I suggest that you spend the most money on servos, then radio, then motor. As a noob, you'll be better off with a smooth motor (Predictable power delivery). Do not buy the 'hottest' motor available. It makes the buggy harder to control. Your money is better spent on quality servos, electronics, and batteries. I also recommend the Futaba HRS. I've not had a lick of trouble with it; it has built in fail-safe features. One of the fastest response times available in the market (REQUIRES Digital Servos though!), if not THE fastest.
I also recommend Hitec servos. Mine have been bullet proof for over a year, and I hear that if you do have a problem with them, just send them in and they'll resolve it without any hassles. I've not heard one single negative response about their customer service yet. In fact, many comments saying that even if the servo was out of warranty, they still repaired or replaced it - no questions asked.
They seem to stand behind their products, and based on my experiences with their stuff thus far, they have my loyalty for the foreseeable future.
Hope this helps!
