I totally understand Buzzardchaser, In that case, just make sure you equip the 35% you decide on with equipment you can use in a 40 % plane later on.
It's mostly the setting up of servos, etc that add up on you quick, but buy the best you can afford so you won't, (hopefully), have to purchase better equipment later on.
On another note that 300sx comp sure looks nice too. I had the 330 and really liked it,.........heck, there all good....
