XRAY - Model racing cars

Ok so I have been a proud Arrma owner in the past but due to issues had to sell off all my rc trucks/cars. Circumstances have changed and money is no longer an issue. I've got the cash and all the time in the world so wanting to get 6 kits to sit and build to race in the future. I will have access to both an indoor and an outdoor track. Indoor is clay and outside is dirt. So these are the 6 categories i'm looking to get.

2 Wheel Drive Buggy 1/10th scale, 4 Wheel Drive Buggy 1/10th scale, 2 Wheel Drive Short Course Truck 1/10th scale, 4 Wheel Drive Short Course Truck 1/10th scale, 4 Wheel Drive Buggy 1/8th scale, 4 Wheel Drive Truggy 1/8th scale

I've owned Losi way back in the day (about 20 years ago) and a couple Arrmas earlier this year. I've seen a lot of names bandied about now on these forums like Tekno, Team Associated, Losi, Serpent, Mugen?, HPI, etc...
